2-Hydroxy-N,N,N-Trimethylethanaminium Tosylate comes from the meeting point of organic chemistry where quaternary ammonium meets sulfonate groups. Its molecular formula, C12H21NO4S, sets the scene for a chemical structure linking the hydroxyethyltrimethylammonium core to a tosylate counterion, offering both hydrophilic and lipophilic features. This material usually appears in forms such as white to colorless crystals, fine powders, or sometimes in small solid flakes. Chemists lean on this particular raw material in laboratories and industrial set-ups for synthesizing ionic liquids, modifying surfaces, or adjusting reaction conditions where both charge stabilization and mild solubility are key. The HS Code for this compound varies between different regions, but it usually falls under the broader class for organo-sulfur compounds, with customs and import authorities referencing it for accurate logistic tracking.
As a chemical intermediate or additive, 2-Hydroxy-N,N,N-Trimethylethanaminium Tosylate stands out for its deliquescent, hygroscopic character. The flakes, powder, or crystalline pearls dissolve in polar solvents, especially water and alcohols, making it valuable in formulation jobs. Its density typically rests in the range of 1.2 to 1.35 g/cm3, according to data from suppliers who document batch-specific sheets for each shipment. This compound sometimes arrives as a free-flowing solid, or as a moist-packed crystal, depending on warehouse storage and climate during shipping. While handling, the chemical’s solid forms need airtight containers to sidestep clumping or breakdown—which often happens due to moisture absorption.
2-Hydroxy-N,N,N-Trimethylethanaminium Tosylate’s backbone features a quaternized nitrogen attached to a hydroxyethyl group, counterbalanced by the para-toluenesulfonate. The structure allows strong ionic associations, yet the hydroxy function promotes both reactivity and solubility tweaks. I have seen this dual nature put to use in catalytic applications, especially in organic transformations where ionic control shapes pathways. Those who work with it recognize that the molecular symmetry and charge spread encourage accurate measurement, whether weighed as flakes, pearls, or finely ground solid in gram-scale reactions or kilo lots—crucial facts for R&D teams scaling up from lab to pilot.
Accuracy in specifications matters for both safety and product performance. High-purity samples rate above 98% by HPLC, according to most suppliers I’ve checked with, and low residual moisture minimizes unwanted hydrolysis. The HS Code, standardized for trade, designates it for international shipment under code 29239000, helping customs officers and buyers trace its journey. Technicians check for melting points in the range of 130–145°C, while the odor—a faint amine note—signals typical storage conditions. Many buyers ask for a certificate of analysis, which documents every property from physical form and color to precise CAS and molecular data for record-keeping. I’ve noticed how customs paperwork often requires this detail, especially in regulated industries such as pharmaceuticals, electronics, and specialty chemicals.
Each form plays a role in different production streams. Powders suit high-surface-area reactions, perfect for catalyst supports or blending in aqueous solutions. Flakes and pearls travel better and reduce dusting; they’re common for large-scale users who need easy dosing by weight or volume. Suppliers sometimes dissolve it as a solution in water or alcohols, given its outstanding solubility and reactivity; these liquid formats save time for industries seeking quick mixing, especially in continuous reactors or automated processes where batch regularity underpins cost control. I’ve seen researchers debate which form to use depending on whether they want quick dissolution or extended shelf life, balancing convenience against stability.
Using 2-Hydroxy-N,N,N-Trimethylethanaminium Tosylate demands respect for both chemical reactivity and personal safety. It’s not classed as highly hazardous or acutely toxic for most users, yet prolonged contact causes skin and eye irritation; operators always reach for gloves and goggles, a lesson reinforced by minor lab accidents. In workplaces, material safety data sheets sit on every bench with warnings: avoid inhaling dust, and never touch eyes or open skin with traces. If a spill happens, the best move involves sweeping into sealable bags and ventilating until residue clears—ignoring this step, as once happened in a partner lab, yields unnecessary risk and cleanup hassle. Effective storage relies on dry, room-temperature environments, as high humidity ruins both appearance and reactivity.
Demand for this molecule stems from its flexibility as a building block in synthetic chemistry, ionic liquids, catalysis, and materials science. In my experience, researchers value the consistent quality and physical properties. Whether ordered as bulk solids for manufacturing or smaller bottles for experimental runs, I’ve seen engineers integrate it as a starting point for multi-step syntheses in specialty sectors—including phase-transfer catalysts, electrolyte components, and coating modifiers, bringing both reliability and reactivity. Buyers should always request batch-specific technical documents, prioritize transparent supplier chains, and verify material origin—smart practices for anyone balancing cost, compliance, and scientific accuracy in today’s climate.
