Chemical Structure

Orlistat Dihydropyranone Impurity CAS 130676-64-1 chemical structure

Description

As a certified reference material (CRM), Orlistat Dihydropyranone Impurity meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

As a process- or degradation-related impurity, Orlistat Dihydropyranone Impurity (CAS 130676-64-1, C22H40O2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Orlistat Dihydropyranone Impurity (C22H40O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
