For procurement managers and R&D scientists in the chemical and pharmaceutical sectors, understanding the critical specifications of Acetoxyacetyl Chloride (CAS 13831-31-7) is crucial for making informed purchasing decisions. When you need to buy this essential organic intermediate, verifying these details with a potential manufacturer or supplier ensures you receive a product that meets your stringent application requirements.

The primary specification for Acetoxyacetyl Chloride is its purity, typically indicated by the assay percentage. Reputable suppliers will guarantee a minimum purity of 97%, with many offering higher grades (e.g., 98.2%) to meet demanding synthetic needs. This high purity is essential for preventing unwanted side reactions and ensuring the integrity of the final product, especially in pharmaceutical applications. Always request a Certificate of Analysis (CoA) from your supplier to confirm the actual batch purity.

Appearance is another key characteristic. Acetoxyacetyl Chloride is generally described as a colorless to pale yellow liquid. Any significant deviation from this description could indicate the presence of impurities or degradation, warranting further investigation. Understanding its physical properties, such as density (around 1.27 g/mL at 25°C) and boiling point (around 55°C/12 mmHg), is also important for handling, storage, and process integration.

Beyond basic purity, buyers should inquire about the presence of specific impurities, especially those that could interfere with subsequent reaction steps. A transparent supplier will provide detailed information on their quality control processes and impurity profiles. Furthermore, consider the packaging specifications. Common packaging for this chemical includes 1kg aluminum foil bags or 25kg fiber drums, designed to maintain product stability and safety during transport and storage.

When sourcing Acetoxyacetyl Chloride from manufacturers in China, it’s beneficial to look for suppliers who offer comprehensive product information, including Material Safety Data Sheets (MSDS) and Technical Data Sheets (TDS). These documents provide vital details on handling, storage, safety precautions, and application guidance. Engaging with a responsive supplier who can answer detailed technical questions and provide product samples is the best approach to securing a reliable supply of high-quality Acetoxyacetyl Chloride for your business needs.
