Description
CATO manufactures Oxybutynin Impurity N1 (Mixture of Diastereomers) 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.
Oxybutynin Impurity N1 (Mixture of Diastereomers) (CAS 1199574-71-4) is a certified pharmaceutical impurity reference standard with the molecular formula C22H35NO3 and a molecular weight of 361.52 g/mol.
The molecular framework of Oxybutynin Impurity N1 (Mixture of Diastereomers) (C22H35NO3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
