For professionals in the pharmaceutical and fine chemical industries, a thorough understanding of chemical specifications is crucial for ensuring the success of synthesis and manufacturing processes. 4-Chloro-3-(trifluoromethyl)phenyl Isocyanate (CAS 327-78-6) is a vital intermediate, and its quality parameters directly influence its utility in producing advanced therapeutics. When you intend to buy this compound, paying close attention to its specifications is a prerequisite for any serious buyer.

The primary specification for 4-Chloro-3-(trifluoromethyl)phenyl Isocyanate is its purity, typically expressed as an assay percentage. For pharmaceutical applications, a minimum purity of 99.0% is generally required. This high level of purity ensures that the chemical participates effectively in intended reactions, such as the synthesis of Sorafenib, without introducing unwanted by-products or contaminants that could compromise the final drug's safety and efficacy. As a dedicated supplier, we ensure our product meets these stringent purity requirements.

Beyond purity, other critical specifications include appearance, which for this compound is often described as a light yellow powder or crystalline solid. Physical properties such as melting point (around 35-36°C), boiling point, and density (approximately 1.4 g/cm³) are also important for handling, storage, and reaction design. These details are readily available from reputable manufacturers and are usually detailed in the product's Certificate of Analysis (CoA).

When sourcing from a manufacturer in China, buyers often look for competitive price points while maintaining these high-quality specifications. This balance is achievable through efficient production processes and economies of scale. Companies frequently search for '4-Chloro-3-(trifluoromethyl)phenyl Isocyanate specifications' or 'CAS 327-78-6 purity' to gather this vital information before deciding where to purchase.

Understanding these specifications is not just about quality control; it's also about ensuring regulatory compliance. The availability of comprehensive documentation, including SDS and CoA, from the supplier is essential. These documents provide detailed safety information and confirm that the product meets all specified quality parameters. By prioritizing these details when you buy, you secure a reliable supply of this critical intermediate.

In summary, when procuring 4-Chloro-3-(trifluoromethyl)phenyl Isocyanate, diligently review its specifications, particularly purity. Partnering with a reliable manufacturer or supplier that offers competitive prices and comprehensive documentation ensures you obtain a high-quality intermediate that meets the rigorous demands of pharmaceutical synthesis.
