Description

9-Pahsa 13C4 is a stable isotope-labeled analog of 9-PAHSA (9-palmitic acid-hydroxystearic acid), a specialized lipid signaling molecule. This high-purity compound is essential for advanced metabolic and lipidomic research, providing an internal standard for precise quantification via mass spectrometry. It is primarily utilized by pharmaceutical R&D teams, academic research institutions, and analytical laboratories focused on diabetes, obesity, and inflammation studies. The product, identified by CAS No. 2748638-71-1, is synthesized to meet the stringent demands of modern bioanalytical applications.

Application

• Internal Standard for LC-MS/MS: Used as a quantitative reference standard in liquid chromatography-tandem mass spectrometry for the accurate measurement of endogenous 9-PAHSA levels in biological matrices.
• Metabolic Pathway Research: Facilitates the study of fatty acid esters of hydroxy fatty acids (FAHFAs) biosynthesis, signaling, and degradation pathways.
• Drug Discovery & Biomarker Validation: Supports target identification and validation in therapeutic programs for metabolic disorders, including type 2 diabetes and insulin resistance.
• Clinical & Pre-clinical Studies: Enables reliable pharmacokinetic and pharmacodynamic analysis in animal models and human clinical trials.
• Lipidomics & Metabolomics: A critical tool in high-throughput profiling to understand lipid metabolism and its role in disease states.
• Quality Control & Method Development: Serves as a benchmark in developing and validating new analytical methods within contract research organizations (CROs) and diagnostic labs.
