For professionals in the chemical and pharmaceutical industries, a deep understanding of the materials they work with is essential. DL-Homocystine (CAS 462-10-2) is a compound of significant interest, particularly as a versatile intermediate. This article aims to provide a comprehensive overview of its properties and synthesis, offering valuable insights for those looking to buy DL-Homocystine. As a leading manufacturer in China, we are committed to transparency regarding the quality and characteristics of our products.

DL-Homocystine, with the molecular formula C8H16N2O4S2 and a molecular weight of 268.35 g/mol, is known for its distinctive disulfide bond. Key physical properties include its appearance as a white to off-white solid, a melting point of 281-284°C (with decomposition), and a density of 1.444 g/cm³. Its solubility is noted as slightly soluble in aqueous acids and bases. Understanding these properties is critical for handling, storage, and application in various chemical processes. For instance, its solid form and relatively high melting point indicate stability under ambient conditions.

The synthesis of DL-Homocystine is an important aspect for buyers and researchers alike. A common method involves the oxidative dimerization of DL-homocysteine or starting from DL-methionine. The process often includes steps like ammonolysis, sodium treatment, and oxidation, culminating in precipitation and purification. For example, one reported synthesis involves treating DL-methionine with ammonia and sodium, followed by oxidation with hydrogen peroxide. The yield and purity can be influenced by reaction conditions and purification techniques. Knowing the synthesis route helps in evaluating potential impurities and ensuring the product meets specific application requirements, especially for pharmaceutical use where strict quality control is necessary.

When sourcing DL-Homocystine, particularly from international suppliers, several factors warrant attention. Beyond product specifications like purity (often cited as 97%+) and CAS number, buyers should inquire about the manufacturer's quality control processes and regulatory compliance. Competitive DL-Homocystine pricing is also a key consideration, but it should not overshadow the importance of product consistency and reliability. Many Chinese manufacturers offer competitive prices, making it an attractive sourcing destination, provided due diligence is performed.

In conclusion, DL-Homocystine (CAS 462-10-2) is a crucial compound with well-defined properties and established synthesis routes. By understanding these aspects and working with reputable suppliers, procurement professionals and researchers can confidently source this valuable pharmaceutical intermediate.
