Chemical companies all over the globe keep their eyes open for the next breakthrough that can drive change in batteries, electrolytes, or advanced materials. 1-2 Ethoxyethyl 3-Methylimidazolium Bis(fluorosulfonyl)imide, known by its CAS number 1440902-44-3, pops up more and more in these conversations. This isn’t a household name, but its impact on clean energy and specialized chemical synthesis speaks loud and clear.
This ionic liquid gives engineers a versatile tool for tuning electrolyte systems. It doesn’t evaporate under normal lab conditions, even at high temperatures, and it shrugs off water. These traits really matter in battery labs, especially with the race to get longer cycle life from lithium batteries or promising next-gen systems. From my own work with chemists in materials science, picking the right ionic liquid isn’t just about stability — it’s also about how it deals with salts, solvents, and temperature swings during cycles. Most of the traditional lithium-ion systems come up short in at least one of those. That’s why chemical teams keep looking for new suppliers and pricing for unique compounds like this one.
One of the top questions from researchers and procurement folks is straightforward: what is the price for 1-2 Ethoxyethyl 3-Methylimidazolium Bis(fluorosulfonyl)imide today? The pricing landscape can jump around. Last month, spot prices ranged from $480 to $614 per 100 grams depending on purity and order size, based on supplier listings in major markets. Production complexity and limited raw material sources press up on cost. Most suppliers operate smaller batches since the user base is still concentrated in advanced R&D settings, meaning bulk discounts don’t stack up the way they might for common chlorides or organic solvents. Through dealings with labs and mid-sized buyers, the single largest influence on price remains the quality requirements, especially when battery-makers aim for extra purity.
Finding a reliable supplier means more than just checking the catalog. Reputation often outranks a marginally lower price, and anyone who’s bought intermediates or solvents knows the cost of an off-spec shipment: delays, lost experiments, and sometimes even scrapped projects. In the case of 1-2 Ethoxyethyl 3-Methylimidazolium Bis(fluorosulfonyl)imide, buyers look hard at the track record for both transparency and after-sales support. One European supplier known for quick-response certificates of analysis caught my own team’s attention because their documentation came through without extra requests, saving us several rounds of clarification.
It isn’t just about purity — responsible chemical companies check their supply chains on sustainability and compliance, especially for regulated markets. Many buyers now request REACH compliance paperwork or registration numbers to avoid future headaches with international shipping. I’ve watched large Asian manufacturers tighten their screening based on this alone.
Traditional solvents and salts flow through massive plant lines. This compound comes together in controlled reactors, where precise temperature and atmosphere control keep side reactions low. Yields can fluctuate based on actual supplier skill, which means a reputable manufacturer has to really understand not just the theory, but the tweaks that improve product batch after batch. Chemistry journals report that less-experienced makers often see visible yellowing or increased water content — flaws that top buyers spot instantly.
For companies moving from kilo-scale synthesis to larger orders, scaling safely and predictably gets tough. The best manufacturers work closely with customers, tuning synthesis and purification steps until results hold steady. This might mean extra vacuum drying, investing in in-line monitoring, or sourcing higher-purity starting materials. It isn’t magic, just close attention and a willingness to invest in the stuff that doesn’t always show up in glossy brochures.
Buying specialty chemicals on the open market carries risk: substitutions, re-labeled drums, improper storage, or delayed delivery. For such advanced ionic liquids, buyers will contact key manufacturers and their accredited distributors, often verifying lot numbers and checking that the CAS number (1440902-44-3) and product naming line up with certificate of analysis and safety sheets. Some research-driven buyers order a small trial batch before going bigger, allowing for hands-on testing under actual process conditions.
Documentation remains crucial. A reliable manufacturer sends a full package: material safety data sheet, batch analysis, sometimes NMR or FTIR scans. This gives peace of mind, especially when moving from benchtop prototypes to multi-liter pilot lines. My own work with battery startups stands as proof—those that cut corners faced repeat issues and wasted weeks, while groups working with proven suppliers had fewer late-night troubleshooting calls.
Specifications build trust between buyers and sellers. For 1-2 Ethoxyethyl 3-Methylimidazolium Bis(fluorosulfonyl)imide, specs often cover purity (commonly 98% or better by NMR), color (near-colorless or faintly yellow liquid), moisture content (usually below 500 ppm), and metal impurities. Some manufacturers tighten this further to suit the needs of high-voltage systems.
Active researchers pay close attention to water content. Even a trace of water can affect battery performance, especially for the latest lithium-sulfur or lithium-air battery prototypes. Others look at the spectral fingerprint to be sure no byproducts slipped through. This sort of due diligence shows up every day in project teams with money on the line, especially in grant-funded programs facing audits.
The specialty chemical field never stands still. As electric vehicles and grid storage tech ramp up, more attention lands on small-run, high-impact materials like 1-2 Ethoxyethyl 3-Methylimidazolium Bis(fluorosulfonyl)imide. Supply chains need to stretch, and companies that bet early on responsible, scalable manufacturing are likely to outpace others stuck to commodity chemicals.
Greater transparency on source, fair pricing, and technical support encourages researchers and product engineers to invest in new chemistry. When suppliers share not just a price list, but knowledge and best-practices from actual manufacturing runs, innovation speeds up. And as industry standards around documentation and compliance rise, those willing to engage on these issues gain loyal repeat buyers.
Each chemical company faces its own pressures — from cost controls to tightening regulations to the race for innovation. Finding the right partner for 1-2 Ethoxyethyl 3-Methylimidazolium Bis(fluorosulfonyl)imide isn’t a single transaction. It means taking pricing, manufacturer track record, documentation, and ongoing support into account. As more companies shift toward higher value-added products, the relationships behind each order will carry as much weight as the specification sheet itself.
