Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 462.84 g/mol gives Oxazepam impurity 14 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Oxazepam impurity 14 (CAS 6801-81-6), a pharmacopoeial impurity reference standard (molecular formula C21H19ClN2O8, MW 462.84 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C21H19ClN2O8, Oxazepam impurity 14 contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 462.84 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 Oxazepam impurity 14 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.
