For procurement managers, R&D scientists, and formulation chemists, a thorough understanding of chemical specifications, storage, and handling is crucial for ensuring product efficacy and safety. DL-Penicillamine (CAS 52-66-4) is no exception. As a widely used pharmaceutical intermediate and research chemical, proper management of this compound is vital. This article provides essential information for those looking to buy DL-Penicillamine and ensure its optimal performance.

Specifications and Purity: DL-Penicillamine is typically supplied as a white crystalline powder. Purity is a key specification, with common grades ranging from ≥96.0% to ≥98.0%, and high-purity grades often reaching ≥99.0%. When sourcing from a DL-Penicillamine manufacturer, always request a detailed Certificate of Analysis (COA). This document should clearly state the assay method, impurity profile, loss on drying, residue on ignition, and heavy metal content. A reputable DL-Penicillamine supplier in China will provide transparent and reliable COAs.

Physical Properties: Melting point for DL-Penicillamine is generally cited between 204-208°C. It is soluble in water (approximately 50 mg/ml) and slightly soluble in alcohol, but generally insoluble in non-polar organic solvents like benzene, ether, and acetone. Understanding these solubility characteristics is important for formulation and experimental design when you plan to purchase DL-Penicillamine.

Storage Recommendations: Optimal storage for DL-Penicillamine is typically at 4°C in a tightly sealed container to protect it from moisture and light, which can degrade the compound over time. Some suppliers may recommend long-term storage at 2-8°C or even -20°C for powders, especially if sensitive to oxidation. Always follow the specific storage instructions provided by your DL-Penicillamine supplier to maintain its integrity and shelf life.

Handling and Safety: When handling DL-Penicillamine, standard laboratory safety precautions should be observed. This includes wearing appropriate personal protective equipment (PPE) such as gloves, eye protection, and lab coats. Ensure adequate ventilation or work in a fume hood, especially when handling larger quantities or if dust is generated. While DL-Penicillamine has pharmaceutical applications, it should be treated as a chemical reagent, and its direct human consumption or application outside of controlled research or manufacturing environments is not advised.
