1-Carboxy-1-Methyl-Pyrrolidinium Bromide stands out in the world of specialty chemicals. This compound holds a unique place thanks to its thoughtful structure—a pyrrolidinium ring with both a carboxylic acid and a methyl group, paired with bromide as the counterion. The molecular formula C6H12BrNO2 gives it a weight around 226.07 g/mol. The presence of both a charged nitrogen center and the carboxylic acid influences not only how the compound behaves but also how it interacts in different solutions, environments, and processes.
From direct experience working in chemical synthesis labs, I know that materials like this get judged not just by their composition but by how they actually sit in your hands and how they blend and dissolve. 1-Carboxy-1-Methyl-Pyrrolidinium Bromide typically appears as a white to off-white solid. You’ll find it as crystalline flakes, powder, or sometimes with a pearl-like look, depending on processing. The density tends to fall in the 1.4–1.6 g/cm3 range, making it a sturdy raw material. It melts in the range of 170–180°C, which keeps it stable for most intended laboratory and industrial uses.
Labeling, inventory, and international trade recognize this chemical through the HS Code 29333999, which supports both customs and regulatory compliance. You can track, store, and sell it in various quantities, from small gram-scale research packs to multi-kilogram drums for industrial needs. Its physical state as a solid powder or flake protects most users from unwanted spillage or airborne dust inhalation. Years in the field remind me that you never want to underestimate even seemingly straightforward solids when it comes to exposure, ventilation, or bulk handling equipment—so tight seals and accurate labelling must always be in place.
In water and polar solvents, this salt dissolves with ease. The ionic structure lets it break down and release both the cation and bromide anion, which is vital for catalysis and ionic liquid applications. As a chemist, I’ve watched it bring stability to complex organic reactions where other materials fall short, especially under mild pH or elevated temperature. The compound’s resistance to degradation keeps processes running smoother and produces sharper yields, cutting waste. Its moderate solubility, typically around 5–10 g per 100 mL at room temperature, offers flexibility for bench work and scale-up processes, from milliliter-level work to liter-scale preparations.
Every chemical has a personality, and this one carries typical traits of its class. Direct contact may cause irritation, so gloves, goggles, and lab coats form your best first line of defense. Inhalation is unlikely except in extreme dust clouds or during cleanup. If you ask industrial users, the safety profile pushes it into the ‘handle responsibly but isn’t extreme’ category. Bromide salts demand respect due to their potential environmental risks—spills and leftovers shouldn’t find their way to local drains or soil. Proper storage, limited exposure, and routine training make this an easy chemical to work with across various sectors, from research to manufacturing.
Raw material sourcing is a direct concern for anyone tracking sustainable and reliable chemical supply chains. The backbone for this compound includes suitable pyrrolidinium derivatives and bromine sources. Production often relies on established synthetic chemistry skills, requiring strong pH control, temperature management, and safe containment of corrosive or reactive intermediates. Having spent years wrestling with supply bottlenecks and inconsistent purity, I stress the need for trusted suppliers and detailed certification on both content and contaminants. Compromises in purity cause headaches later on, ruining syntheses, or requiring costly downstream purification.
The true worth of 1-Carboxy-1-Methyl-Pyrrolidinium Bromide appears most clearly in processes that depend on its dual ionic and acidic nature. I have seen this in emerging work on ionic liquids, where high polarity and chemical stability enhance both performance and processability. Its solid form supports safe, compact shipping and storage, reducing logistical overhead. In catalysis, it brings unique selectivity and can help unlock transformations not possible with traditional mineral acids or salts. In pharmaceuticals and fine chemicals, strict attention to contaminants becomes crucial to prevent downstream purity failures, so documentation and process scrutiny span every batch.
Even reliable compounds come with catch points. I have faced inconsistent supply, packaging problems, and occasional confusion around naming conventions. Detailed labeling, batch traceability, and close communication between buyers and suppliers ensure smooth workflow. Waste management also demands attention—neutralizing acid residues, capturing bromide for recycling, and minimizing losses all count toward responsible stewardship. Moving forward, companies and researchers alike need to invest in greener manufacturing methods, refine purification processes, and ramp up transparency around environmental footprints. Collaboration across supply chains and clearer hazard communication should cut delays, protect workers, and build stronger confidence in chemical supply markets.
