Description

Flufenamic Acid-13C6 is a stable isotope-labeled analog of the non-steroidal anti-inflammatory drug (NSAID) flufenamic acid, where six carbon atoms are replaced with the 13C isotope. This compound is an essential internal standard for the precise and accurate quantification of flufenamic acid in complex biological matrices using advanced analytical techniques like LC-MS/MS. It is primarily required by pharmaceutical R&D laboratories, contract research organizations (CROs), and analytical testing facilities engaged in pharmacokinetic studies, drug metabolism research, and bioanalytical method development.

Application

• Use as an internal standard for the quantitative analysis of flufenamic acid in bioanalytical assays.
• Critical component in LC-MS/MS method development and validation for drug discovery and development.
• Application in pharmacokinetic (PK) and pharmacodynamic (PD) studies to track drug absorption, distribution, metabolism, and excretion.
• Supporting metabolite identification and profiling research in pharmaceutical sciences.
• Utilization in clinical and pre-clinical research to ensure data accuracy and regulatory compliance.
• Essential for quality control and assurance in the manufacturing of flufenamic acid and related pharmaceutical products.
