For professionals in the pharmaceutical and fine chemical industries, understanding the specifications of chemical building blocks is fundamental to successful research, development, and manufacturing. These specifications are not merely data points; they are critical indicators of a chemical's suitability for a particular application, especially when dealing with complex synthesis routes. Let's explore the key specifications that buyers should consider when looking to buy (S)-2-Amino-5-methoxytetralin (S)-mandelate (CAS 439133-67-2).

The first specification to scrutinize is Purity. For (S)-2-Amino-5-methoxytetralin (S)-mandelate, a purity of ≥99% is often required. This high level of purity ensures that the intermediate will behave predictably in synthesis and minimizes the introduction of contaminants into the final product. Suppliers should provide verifiable purity data, typically obtained through techniques like High-Performance Liquid Chromatography (HPLC) or Gas Chromatography (GC).

Appearance is another important visual cue. (S)-2-Amino-5-methoxytetralin (S)-mandelate is commonly described as a white powder. Any significant deviation from this description, such as discoloration or a different physical form, could indicate contamination or degradation.

CAS Number (439133-67-2) and Molecular Formula (C19H23NO4) are essential identifiers. These unique identifiers ensure that you are procuring the correct chemical compound, eliminating ambiguity in ordering and inventory management. Cross-referencing these details with the supplier's information is a crucial step.

For chiral molecules like (S)-2-Amino-5-methoxytetralin (S)-mandelate, Stereochemistry is paramount. While the name itself specifies the (S) configuration, confirmation of enantiomeric purity (enantiomeric excess or ee) through chiral chromatography or optical rotation measurements is often necessary for sensitive applications.

When sourcing from a manufacturer in China, also look for information on Packaging and Storage Conditions. Proper packaging protects the chemical during transit and storage, while recommended storage conditions (e.g., refrigeration) help maintain its stability and quality. By diligently reviewing these specifications, procurement managers and researchers can make informed decisions and ensure they are acquiring reliable, high-quality chemical building blocks for their critical projects.
