Chemical Structure

Sorbitol EP Impurity B CAS 25878-23-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 182.17 g/mol gives Sorbitol EP Impurity B distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Sorbitol EP Impurity B (CAS 25878-23-3), a pharmacopoeial impurity reference standard (molecular formula C6H14O6, MW 182.17 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Sorbitol EP Impurity B (C6H14O6) is characterized by a carbohydrate-derived structure. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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.

CATO manufactures Sorbitol EP Impurity B under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
