Description
CATO manufactures Ambroxol Impurity 33 HCl 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.
CATO supplies Ambroxol Impurity 33 HCl (CAS 101900-44-1), a pharmacopoeial impurity reference standard (molecular formula C13H19BrN2OHCl, MW 335.67 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C13H19BrN2OHCl, Ambroxol Impurity 33 HCl contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 335.67 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
