Description
CATO manufactures Chlorpheniramine Impurity 11（ Maleate Salt） 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.
Chlorpheniramine Impurity 11（ Maleate Salt） (CAS 23052-94-0) is a certified pharmaceutical impurity reference standard with the molecular formula C14H15ClN2C4H4O4 and a molecular weight of 362.81 g/mol.
The molecular framework of Chlorpheniramine Impurity 11（ Maleate Salt） (C14H15ClN2C4H4O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
