Chemical Structure

Chlorhexidine Digluconate Solution EP Impurity L CAS CATO-C4X-225637 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 330.72 g/mol gives Chlorhexidine Digluconate Solution EP Impurity L distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Chlorhexidine Digluconate Solution EP Impurity L (CAS CATO-C4X-225637), a pharmacopoeial impurity reference standard (molecular formula C13H15ClN2O6, MW 330.72 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Chlorhexidine Digluconate Solution EP Impurity L is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 330.72 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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 Chlorhexidine Digluconate Solution EP Impurity L 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.
