Propranolol Impurity 63 CAS CATO-C4X-151963 chemical structure

Description

CATO manufactures Propranolol Impurity 63 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.

Propranolol Impurity 63 (CAS CATO-C4X-151963) is a certified pharmaceutical impurity reference standard with the molecular formula C16H19NO and a molecular weight of 241.33 g/mol.

Propranolol Impurity 63 (C16H19NO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
