Chemical Structure
Description
The occurrence of Oxybutynin hydrochloride-phenyl-d<SUB>5</SUB> is closely related to deuterium isotope labeling, a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Oxybutynin hydrochloride-phenyl-d<SUB>5</SUB> (CAS 1173019-04-9) is a high-purity analytical reference standard with the molecular formula C22H32D5NO3HCl and a molecular weight of 405.03 g/mol.
The molecular framework of Oxybutynin hydrochloride-phenyl-d<SUB>5</SUB> (C22H32D5NO3HCl) is characterized by deuterium isotope labeling, a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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. 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 analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
