For researchers and procurement specialists in the pharmaceutical industry, a thorough understanding of technical specifications is non-negotiable when sourcing chemical compounds. This is particularly true for complex pharmaceutical intermediates such as (3aR,7aR)-4'-(1,2-Benzisothiazol-3-yl)octahydrospiro[2H-isoindole-2,1'-piperazinium] Methanesulfonate, identified by CAS 186204-37-5.
The primary technical detail of interest for this compound is its purity. Manufacturers typically offer CAS 186204-37-5 at purities of 95% or higher, with 97% or 99% being common for advanced applications. This high purity is critical, as impurities can significantly impact downstream reactions and the final drug product's efficacy and safety profile.
Appearance is another important specification. Octahydrospiro[2H-isoindole-2,1'-piperazinium] Methanesulfonate is generally described as a white to off-white solid. Any significant deviation from this appearance may indicate contamination or degradation, warranting further investigation.
The molecular formula (C19H26N4O3S2) and molecular weight (approximately 422.56 g/mol) are fundamental identifiers. These parameters are essential for stoichiometric calculations in synthetic procedures and for analytical characterization.
For specialized applications, the stereochemistry is paramount. The '(3aR,7aR)' designation indicates a specific spatial arrangement of atoms, which is crucial for the compound's biological activity when used as an intermediate in chiral drug synthesis. Manufacturers must ensure enantiomeric purity is maintained.
Understanding the solubility profile, typically slight solubility in chloroform and methanol, is also beneficial for process development and analytical method design. While specific melting points might be provided, they can vary slightly based on purity and crystalline form.
When purchasing from a manufacturer, always request a detailed Certificate of Analysis (CoA). This document should clearly state all relevant specifications, including purity, appearance, identification methods, and the batch number, providing assurance of the product's quality and suitability for your intended use. For those looking to buy this critical intermediate, verifying these technical specifications with the supplier is a cornerstone of informed procurement.
