For professionals in the chemical and pharmaceutical industries, a thorough understanding of key intermediates is essential for successful operations. 2-Cyano-phenothiazine (CAS 38642-74-9) is one such compound, valued for its role as a pharmaceutical intermediate, particularly in the synthesis of antipsychotic drugs. This article aims to provide insights into its properties, purity standards, and the purchasing process.

The typical 'appearance' of 2-Cyano-phenothiazine is described as a yellow crystalline powder. This physical characteristic is important for initial identification and handling. Beyond appearance, 'assay' is a critical parameter, with manufacturers typically guaranteeing a purity of 98.5% or 99.0% minimum. For R&D scientists and formulators, high purity is crucial to ensure the efficacy and safety of the final pharmaceutical products. When searching for this chemical, terms like '2-cyano-phenothiazine purity' or 'CAS 38642-74-9 assay' are commonly used.

Understanding the 'typical properties' also includes knowledge of its molecular formula (C13H8N2S), molecular weight (224.28), and melting point (around 191-193°C from some sources, or ≥202°C for identification via HPLC). These details are vital for chemists planning synthesis reactions and for quality control departments verifying incoming materials. Buyers often inquire about '2-cyano-phenothiazine quality standard' to ensure it meets their project's specific requirements.

When it comes to purchasing, procurement managers often look for a '2-cyano-phenothiazine CAS 38642-74-9 supplier' or 'manufacturer in China' offering competitive 'prices'. The decision to 'buy 2-cyano-phenothiazine' should be based on a combination of factors: the supplier's reputation, their ability to provide consistent quality, and their responsiveness to inquiries. Requesting a quotation often involves specifying desired quantities and purity levels.

Moreover, reliable suppliers will provide comprehensive documentation, including Technical Data Sheets (TDS) and Material Safety Data Sheets (MSDS), which detail handling, safety, and storage recommendations. Proper storage, usually in a cool, dry place, is essential to maintain the compound's integrity. For those involved in custom synthesis or drug discovery, securing a dependable source for high-quality 2-Cyano-phenothiazine is a foundational step.

In summary, a thorough understanding of 2-Cyano-phenothiazine's appearance, purity standards, and key chemical properties, coupled with a strategic approach to sourcing from reliable manufacturers, ensures successful procurement for pharmaceutical and chemical applications. This diligence is fundamental for any organization looking to purchase this critical intermediate.
