For any chemical intermediate, particularly those used in sensitive applications like pharmaceutical research and fine chemical synthesis, understanding its precise technical specifications and safety data is non-negotiable. 6-Chloro-2,3-dioxo-1,2,3,4-tetrahydroquinoxaline, CAS 6639-79-8, is no exception. This guide provides essential information for professionals looking to purchase and utilize this compound safely and effectively.

Chemically known as 6-chloro-1,4-dihydroquinoxaline-2,3-dione, this compound typically presents as a brown to dark brown solid. Its molecular formula is C8H5ClN2O2, with a molecular weight of approximately 196.59 g/mol. Key physical and chemical properties often cited include a melting point generally above 350°C, indicating high thermal stability. While specific solubility data can vary, it's important to consult the supplier's documentation for detailed information relevant to your intended application.

The compound's primary application is in pharmaceutical research, where its function as a glycine receptor antagonist is of significant interest. This activity underlies its potential use in developing analgesics, anticonvulsants, neuroprotectants, and sedative-hypnotic agents. For chemists and formulators, these properties dictate its role as a valuable building block in complex organic synthesis pathways.

Safety data is a critical aspect for any chemical handling. Safety Data Sheets (SDS) for 6-Chloro-2,3-dioxo-1,2,3,4-tetrahydroquinoxaline typically classify it with hazard statements such as 'Causes skin irritation,' 'Causes serious eye irritation,' and 'May cause respiratory irritation.' Consequently, appropriate personal protective equipment (PPE) is essential when handling this material. This includes wearing chemical-resistant gloves (e.g., nitrile), safety goggles with side shields, and ensuring adequate ventilation in the work area. In case of inhalation, moving to fresh air and seeking medical attention is recommended. For skin or eye contact, immediate washing with plenty of water is advised.

When sourcing this compound, particularly from manufacturers in China, always demand a comprehensive SDS that complies with GHS (Globally Harmonized System of Classification and Labelling of Chemicals) standards. This document will provide detailed guidance on handling, storage, emergency procedures, and disposal. Understanding these specifications and safety protocols is fundamental for any researcher or procurement manager planning to buy CAS 6639-79-8, ensuring both the success of their project and the safety of their personnel.
