Understanding the chemical profile and quality assurance protocols for DL-Cysteine Hydrochloride (CAS 10318-18-0) is crucial for any buyer in the chemical and pharmaceutical sectors. As a distinguished manufacturer and supplier, we are committed to transparency regarding the chemistry and quality control of our products.
DL-Cysteine Hydrochloride is the hydrochloride salt of the amino acid cysteine, existing as a racemic mixture of D- and L-cysteine. Its molecular formula is C3H7NO2S•HCl, with a molecular weight of approximately 157.61 g/mol. Typically presented as a colorless crystal or white crystalline powder, its physical properties are vital for handling and formulation. Key specifications often include a melting point around 225°C and solubility in water, sometimes requiring the addition of hydrochloric acid for complete dissolution. These characteristics are critical for its use as a pharmaceutical intermediate and food additive.
Our quality control process for DL-Cysteine Hydrochloride begins with the careful selection of raw materials and extends through every stage of synthesis and purification. We employ advanced analytical techniques to verify purity, identity, and compliance with specified parameters. Standard testing includes techniques like Thin Layer Chromatography (TLC) to confirm purity (typically ≥95%), Infrared Spectroscopy (IR) for identification, and assays for carbon and nitrogen content. For pharmaceutical applications, meeting specific pharmacopoeial standards might also be a requirement, which we are equipped to address.
The stability and handling of DL-Cysteine Hydrochloride are also important considerations. While generally stable, it is recommended to store it in a dark, inert atmosphere at room temperature to maintain its integrity. Its hygroscopic nature also means proper packaging, such as airtight aluminum foil bags, is essential for preserving quality during transit and storage. We ensure our packaging solutions protect the product from moisture and degradation.
When you choose to buy DL-Cysteine Hydrochloride from us, you are choosing a supplier that places a strong emphasis on product integrity and scientific validation. We invite you to discuss your specific quality requirements with our technical team and request a detailed quotation for your bulk procurement needs. Partner with a manufacturer dedicated to providing high-quality DL-Cysteine Hydrochloride.
