In the rigorous domain of pharmaceutical manufacturing, the quality of every single ingredient, especially chemical intermediates, is scrutinized to ensure the safety and efficacy of the final drug product. L-2-Aminobutyric Acid Hydrochloride (CAS 5959-29-5) is a prime example of an intermediate where purity is not just a specification but a critical determinant of its suitability. For R&D scientists and procurement managers tasked with sourcing this compound, understanding the nuances of its purity is paramount when considering a purchase.

L-2-Aminobutyric Acid Hydrochloride, also known as Homoalanine Hydrochloride, is a chiral amino acid derivative. Its specific stereoisomeric form, typically the (S)-enantiomer, is essential for its role in stereoselective synthesis. Impurities, whether they are other stereoisomers, residual solvents, unreacted starting materials, or by-products from the synthesis process, can significantly impact the outcome of subsequent reactions. For instance, in the synthesis of Levetiracetam, the presence of isomeric impurities could lead to the formation of undesired side products, reducing the overall yield and potentially compromising the drug's therapeutic profile.

Manufacturers specializing in high-value fine chemicals and pharmaceutical intermediates understand this critical need for purity. They employ advanced analytical techniques, such as High-Performance Liquid Chromatography (HPLC) and Nuclear Magnetic Resonance (NMR) spectroscopy, to verify the identity, purity, and enantiomeric excess (ee) of L-2-Aminobutyric Acid Hydrochloride. Reports often cite purity levels exceeding 99% and enantiomeric excess around 99.4%, indicative of high-quality production. When you buy this intermediate, always request a Certificate of Analysis (CoA) that clearly states these purity metrics.

Sourcing from reputable manufacturers, especially those based in established chemical production regions like China, can provide assurance of quality. These suppliers are accustomed to meeting the stringent demands of the pharmaceutical industry. By working with experienced suppliers, buyers can be confident that the L-2-Aminobutyric Acid Hydrochloride they procure will meet the necessary specifications, facilitating smooth synthesis processes and contributing to the development of safe and effective pharmaceuticals. This focus on purity is a non-negotiable aspect when buying critical chemical intermediates.
