Description

5-Hydroxy Flunixin-D3 is a deuterated internal standard of the primary metabolite of Flunixin, a non-steroidal anti-inflammatory drug (NSAID). This high-purity reference material is essential for ensuring the accuracy and reliability of quantitative analytical methods. It is primarily used by analytical laboratories and research institutions in the pharmaceutical and veterinary sectors for method development, validation, and routine testing.

Application

• Quantitative Analytical Reference Standard: Serves as a critical internal standard for the precise quantification of Flunixin and its metabolites in complex biological matrices via LC-MS/MS and HPLC.
• Veterinary Drug Residue Analysis: Enables accurate monitoring and compliance testing for Flunixin residues in food-producing animals, such as cattle and swine, to ensure food safety.
• Pharmacokinetic and Metabolism Studies: Used in research to study the absorption, distribution, metabolism, and excretion (ADME) profile of Flunixin in various species.
• Method Development & Validation: A key component in developing and validating robust, regulatory-compliant analytical methods for quality control and research purposes.
• Doping Control in Equine Sports: Supports testing protocols for the detection of prohibited substances in racehorses and performance animals.
