For B2B procurement professionals, especially those in technical fields like pharmaceuticals and advanced materials, understanding chemical specifications is fundamental to making informed purchasing decisions. Key identifiers such as CAS numbers and purity levels are not mere technical jargon; they are critical indicators of a chemical's identity, quality, and suitability for specific applications. As a leading chemical supplier, we emphasize the importance of clear and accurate specification data.

The Chemical Abstracts Service (CAS) Registry Number, like CAS: 1354227-36-3 for Carbamic Acid, N-[(1S,2R)-1-ethyl-2-hydroxypropyl]-, 1,1-dimethylethyl Ester, serves as a unique identifier for chemical substances. It ensures that buyers and manufacturers are referring to the exact same compound, eliminating ambiguity. When you search for chemical intermediates, using the correct CAS number is the most reliable way to find the specific product you need. We list the CAS number prominently for all our products, facilitating precise sourcing.

Purity is another critical specification. For pharmaceutical intermediates, even small impurities can have significant consequences on the efficacy and safety of the final drug product. Manufacturers typically provide purity levels, often determined by techniques like Gas Chromatography (GC) or High-Performance Liquid Chromatography (HPLC). For our high-quality pharmaceutical intermediates, we ensure rigorous purity standards are met and clearly communicated. For example, when you buy Carbamic Acid, N-[(1S,2R)-1-ethyl-2-hydroxypropyl]-, 1,1-dimethylethyl Ester from us, you can rely on documented purity levels.

Beyond these core specifications, manufacturers often provide additional data such as appearance, melting point, solubility, and analytical reports (e.g., NMR, Mass Spectrometry). This comprehensive manufacturer data builds trust and confirms the product's quality. When evaluating suppliers, look for those who readily provide detailed specifications and certifications. By prioritizing these details, procurement managers can confidently buy chemicals that align with their project's requirements, ensuring quality and consistency from reputable sources in China and beyond.
