DL-Methionine, identified by the CAS number 59-51-8, is a fundamental sulfur-containing amino acid that plays a pivotal role across various industries, most notably in animal nutrition, pharmaceuticals, and cosmetics. Understanding its chemical properties, production methods, and the importance of reliable sourcing is crucial for businesses that utilize this versatile compound. NINGBO INNO PHARMCHEM CO.,LTD., as a prominent manufacturer and supplier based in China, offers valuable insights into DL-Methionine's profile and procurement.

Chemically, DL-Methionine is a racemic mixture of the D- and L- isomers of methionine. It presents as a white crystalline powder with a characteristic odor. Its molecular formula is C5H11NO2S, and its molecular weight is approximately 149.21 g/mol. Key physical properties include a melting point around 280-284°C (with decomposition) and a relatively low solubility in water, though it dissolves better in dilute acids and alkali hydroxides. This compound is stable under normal storage conditions but is incompatible with strong oxidizing agents.

The industrial-scale production of DL-Methionine primarily relies on chemical synthesis. A common pathway involves the reaction of methyl mercaptan with acrolein, followed by subsequent steps including the formation of a hydantoin intermediate, which is then hydrolyzed. This multi-step synthetic process allows for large-scale manufacturing, making DL-Methionine an economically viable ingredient for widespread industrial use. The efficiency and optimization of this synthesis are critical for manufacturers aiming to provide high-purity DL-Methionine at competitive prices.

As a vital building block for proteins and a precursor to essential metabolites, DL-Methionine's applications are diverse. In animal feed, it is indispensable for growth, feather development, and overall health in poultry and livestock. In the pharmaceutical realm, it serves roles in liver protection and as an antioxidant precursor. The cosmetic industry utilizes its conditioning properties for hair and skin care.
