For procurement specialists and R&D chemists, scrutinizing the specifications of chemical intermediates is a non-negotiable part of the sourcing process. This is particularly true for compounds like 9,10-Bis(phenylethynyl)-2-methylanthracene (CAS 51580-23-5), a key ingredient in various industrial applications, primarily within the daily chemical sector.

The primary identifier for this compound is its CAS number: 51580-23-5. When looking to buy 9,10-Bis(phenylethynyl)-2-methylanthracene, the most critical specification is its assay, which typically needs to be high, often at 98%. This purity level ensures predictable reaction outcomes and consistent product performance in downstream applications. A certificate of analysis (CoA) from the manufacturer is essential to verify this purity.

Another key characteristic is the appearance. 9,10-Bis(phenylethynyl)-2-methylanthracene is commonly described as an orange crystal solid. This visual cue aids in identification and can sometimes indicate the quality or processing conditions. Variations in color or form might signal impurities or degradation, making it important to match the delivered product with the supplier's stated appearance.

Beyond assay and appearance, other important properties that buyers often consider include molecular weight (392.49 g/mol) and melting point (225–226°C). These physical properties are fundamental for handling, storage, and integration into manufacturing processes. Understanding these specifications helps in selecting the right manufacturer and ensuring the intermediate meets the technical requirements of your formulation or synthesis.

When contacting potential suppliers for 9,10-Bis(phenylethynyl)-2-methylanthracene, always request detailed specifications and a CoA. This due diligence is vital for securing a reliable supply of this important chemical intermediate. Manufacturers in China are a significant source, and focusing on those who clearly list these key specifications will streamline your procurement process.
