Description

Rac Desethyl Oxybutynin-D5 Hydrochloride CAS NO 1173147-63-1 is a deuterated isotopologue of a key oxybutynin metabolite, specifically designed for use as an internal standard in quantitative bioanalytical methods. This high-purity reference material is critical for ensuring the accuracy and reliability of pharmacokinetic and metabolic studies, particularly in the development and quality control of pharmaceutical products. It is an essential tool for analytical laboratories and research institutions focused on urology, drug metabolism, and forensic toxicology.

Application

• Internal Standard for LC-MS/MS: Primary application as a stable, isotopically labeled internal standard for the precise quantification of desethyl oxybutynin and related compounds in complex biological matrices like plasma, serum, and urine.
• Pharmacokinetic & Metabolism Studies: Enables accurate tracking of drug absorption, distribution, metabolism, and excretion (ADME) for oxybutynin and its derivatives in clinical and pre-clinical research.
• Pharmaceutical R&D & Quality Control: Supports method development and validation in the research, development, and batch release testing of antimuscarinic and overactive bladder (OAB) medications.
• Forensic & Clinical Toxicology: Used in assays to confirm the presence and concentration of oxybutynin metabolites in forensic investigations or therapeutic drug monitoring (TDM) programs.
• Biomarker Research: Facilitates the study of metabolic pathways and the identification of potential biomarkers related to anticholinergic drug therapy.

Quality Control

Every batch of Rac Desethyl Oxybutynin-D5 Hydrochloride is manufactured and analyzed under strict quality management systems. We guarantee high chemical and isotopic purity, supported by comprehensive analytical data including NMR, HPLC, and mass spectrometry. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming identity, purity (typically ≥95% by HPLC), isotopic enrichment, and other critical parameters to ensure suitability for sensitive analytical applications.

Storage

Preserve in a tightly closed container, protected from light. Store at controlled room temperature (15-25°C) or as indicated on the label. This compound is hygroscopic (moisture-sensitive); keep the container tightly sealed in a dry environment to prevent degradation. For long-term storage, consider desiccant use.
