For procurement managers and R&D scientists, a thorough understanding of product specifications is fundamental when sourcing chemical intermediates. 2-Methoxyphenothiazine, identified by CAS 1771-18-2, is no exception. Ensuring that this compound meets the necessary quality standards is crucial for its successful application in organic synthesis and pharmaceutical manufacturing.

The primary specification buyers look for in 2-Methoxyphenothiazine is its purity, typically expressed as an assay percentage. A minimum assay of ≥98% is commonly required, especially for pharmaceutical applications where even trace impurities can affect the final product’s efficacy and safety. Suppliers often back this purity with certifications such as GMP (Good Manufacturing Practice) and SGS, providing an extra layer of assurance.

The physical appearance of 2-Methoxyphenothiazine is also a key detail. It is generally described as a light yellow or light gray solid. This visual cue, along with its molecular formula (C13H11NOS) and molecular weight (229.3), helps in confirming the identity and quality of the material upon receipt. Standard packaging, often in 25kg drums, is another practical specification for industrial procurement.

When you are ready to buy 2-Methoxyphenothiazine, it’s important to make an inquiry to manufacturers or suppliers that clearly list these specifications. These details are vital for R&D scientists formulating new processes or for production managers ensuring batch consistency. Understanding the quality standards, such as adherence to USP, BP, or EP monographs, can streamline your purchasing decisions.

For those seeking to source 2-Methoxyphenothiazine, especially from China, prioritizing suppliers who are transparent about their quality control processes and product specifications is recommended. A competitive price is important, but it should not overshadow the need for a high-quality, well-characterized intermediate. Always request the latest Technical Data Sheets (TDS) and Certificates of Analysis (CoA) when making a purchase decision.
