Description

9-Pahsa-D9 is a deuterated chemical compound, specifically a perdeuterated analog of 9-PAHSA (9-palmitic acid-hydroxystearic acid), identified by CAS NO 1809222-43-2. This high-purity, isotopically labeled standard is critical for advanced analytical research, providing unmatched precision in metabolic and lipidomic studies. It is an essential tool for pharmaceutical R&D, academic research, and analytical laboratories requiring stable isotope-labeled internal standards for mass spectrometry and other quantitative techniques.

Application

• As a stable isotope-labeled internal standard for the accurate quantification of endogenous 9-PAHSA in biological matrices via LC-MS/MS.
• For metabolic pathway tracing and lipid metabolism research in preclinical studies.
• Use in pharmaceutical development for pharmacokinetic (PK) and pharmacodynamic (PD) studies of fatty acid esters of hydroxy fatty acids (FAHFAs).
• Critical component in diagnostic assay development for metabolic disorders such as diabetes and insulin resistance.
• Supporting academic research into the biological roles and signaling functions of specialized pro-resolving lipid mediators.
• For quality control and method validation in clinical and analytical laboratories.

Quality Control

Every batch of 9-Pahsa-D9 is manufactured and analyzed under strict quality management systems to ensure the highest isotopic and chemical purity required for sensitive analytical applications. Our products undergo rigorous quality testing, including NMR and mass spectrometry, to ensure compliance with industry standards for isotopic enrichment and chemical identity. Certificates of Analysis (COA) detailing batch-specific purity, isotopic enrichment (typically >98% D), and impurity profiles are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below under an inert atmosphere. This product is hygroscopic (moisture-sensitive). Allow the sealed vial to equilibrate to room temperature before opening to minimize moisture absorption.
