Chemical Structure

Flunarizine Impurity 31 CAS CATO-C4X-135731 chemical structure

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Flunarizine Impurity 31 is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 231.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Flunarizine Impurity 31 (CAS CATO-C4X-135731) is a certified pharmaceutical impurity reference standard with the molecular formula C13H17N3O and a molecular weight of 231.29 g/mol.

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 Flunarizine Impurity 31 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.
