The intricate world of organic chemistry and biochemistry is populated by a vast array of molecules, each with unique properties and applications. L-Cysteic acid, identified by CAS number 498-40-8, is a fascinating amino acid derivative that warrants attention for its chemical characteristics and its role in various scientific disciplines. As a derivative of L-cysteine, it carries an additional sulfonic acid group, distinguishing it significantly from its precursor. For researchers and chemists seeking to buy L-cysteic acid, understanding its fundamental properties is the first step.

Chemically, L-cysteic acid is characterized by its amino group (-NH2), carboxylic acid group (-COOH), and a sulfonic acid group (-SO3H) attached to the beta-carbon. This sulfonic acid group imparts a higher acidity compared to typical carboxylic acids and contributes to its unique chemical behavior, including its water solubility. Its molecular weight is approximately 169.15 g/mol. The compound typically appears as a white to off-white crystalline powder. Its melting point is noted to be around 260°C with decomposition, indicating good thermal stability for a molecule of its nature.

The utility of L-cysteic acid spans several research areas. Primarily, it is recognized as a metabolite of L-cysteine, making it relevant for metabolic studies. Its role in understanding oxidation processes, particularly the conversion of thiol groups to sulfonic acids, is crucial for research into oxidative stress and related biological phenomena. Scientists also employ L-cysteic acid in studies involving enzyme kinetics, either as a substrate or an inhibitor, to elucidate enzyme pathways and mechanisms. Furthermore, its incorporation into synthetic peptides allows for the exploration of how this altered amino acid structure impacts peptide function and interaction.

For procurement professionals and researchers, sourcing reliable chemical intermediates is key. A reputable L-cysteic acid supplier, often found among the many specialized chemical manufacturers in China, can provide the necessary quality and consistency. When considering L-cysteic acid price, it's important to evaluate the purity levels, packaging options, and the overall service provided by the manufacturer. Ensuring compliance with quality standards and receiving comprehensive documentation, such as SDS and CoA, are also critical aspects of a successful purchase.

In conclusion, L-cysteic acid is a chemically significant compound with a growing role in diverse scientific applications. By understanding its properties and identifying reliable sources for purchase, researchers can effectively leverage this amino acid derivative in their critical work, contributing to advancements in biochemistry, medicine, and materials science.
