Indobufen Impurity 33 CAS 937671-41-5

Description

Compared with other compounds in its class, the molecular weight of 179.22 g/mol gives Indobufen Impurity 33 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Indobufen Impurity 33 (CAS 937671-41-5), a pharmacopoeial impurity reference standard (molecular formula C10H13NO2, MW 179.22 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Indobufen Impurity 33 (C10H13NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 179.22 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 Indobufen Impurity 33 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.
