Description

Flavoxate-D4 Hydrochloride CAS NO 1189678-43-0 is a deuterium-labeled analog of the antispasmodic agent flavoxate hydrochloride, serving as a critical internal standard for precise quantitative analysis. This high-purity, isotopically labeled compound is essential for ensuring accuracy and reliability in advanced analytical techniques, particularly in pharmacokinetic and metabolic studies. It is primarily required by pharmaceutical R&D laboratories, contract research organizations (CROs), and analytical testing facilities engaged in method development and validation.

Application

• Internal Standard for LC-MS/MS and GC-MS analysis in bioanalytical studies.
• Quantitative reference material for pharmacokinetic (PK) and bioavailability research.
• Method development and validation in pharmaceutical quality control laboratories.
• Metabolite identification and drug metabolism studies (DMPK).
• Use in clinical research for accurate measurement of flavoxate and its metabolites.
• Calibration standard for ensuring regulatory compliance in analytical testing (e.g., FDA, EMA submissions).
