Description

4-Hydroxy Xylazine is a key chemical intermediate and metabolite of the veterinary sedative Xylazine. This compound is of significant importance for pharmaceutical research, analytical method development, and forensic toxicology. It is primarily required by research institutions, pharmaceutical manufacturers, and analytical laboratories for use in reference standards, metabolite studies, and the development of detection assays.

Application

• Pharmaceutical Reference Standard: Used as a certified reference material (CRM) for the calibration of analytical instruments and validation of testing methods in quality control laboratories.
• Metabolite Research: Serves as a critical standard in pharmacokinetic and metabolic pathway studies of Xylazine in veterinary and forensic science.
• Analytical Method Development: Essential for developing and optimizing high-performance liquid chromatography (HPLC), liquid chromatography-mass spectrometry (LC-MS), and other chromatographic assays.
• Forensic Toxicology: Employed as a calibrant and control in the detection and quantification of Xylazine and its metabolites in biological samples for forensic investigations.
• Veterinary Pharmaceutical R&D: Used in research focused on the safety, efficacy, and metabolic profile of sedative agents.
• Chemical Synthesis Intermediate: Acts as a building block for the synthesis of more complex molecules or labeled analogs for research purposes.
