Chemical Structure

9,10,12-trihydroxystearic acid CAS 25027-95-6 chemical structure

Description

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.

9,10,12-trihydroxystearic acid (CAS 25027-95-6), molecular formula C18H36O5 and molecular weight 332.48 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 9,10,12-trihydroxystearic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 332.48 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
