Cisatracurium Besilate EP Impurity F Benzenesulfonate CAS 1100676-16-1

Description

Compared with other compounds in its class, the molecular weight of 673.82 g/mol gives Cisatracurium Besilate EP Impurity F Benzenesulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Cisatracurium Besilate EP Impurity F Benzenesulfonate (CAS 1100676-16-1), a pharmacopoeial impurity reference standard (molecular formula C29H42NO7C6H5O3S, MW 673.82 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Cisatracurium Besilate EP Impurity F Benzenesulfonate is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 673.82 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

CATO manufactures Cisatracurium Besilate EP Impurity F Benzenesulfonate 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.
