Sorbitol Impurity 5 CAS CATO-C4X-25325 chemical structure

Description

CATO supplies Sorbitol Impurity 5 (CAS CATO-C4X-25325), a pharmacopoeial impurity reference standard (molecular formula C13H26O10, MW 342.34 g/mol) used for the identification and quantification of trace impurities in APIs.

Sorbitol Impurity 5 (C13H26O10) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

As a certified reference material (CRM), Sorbitol Impurity 5 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.
