Chemical Structure

12-Oxystearic acid sodium salt CAS 73536-57-9 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies 12-Oxystearic acid sodium salt (CAS 73536-57-9), a certified reference material (molecular formula C18H33O3Na, MW 320.45 g/mol) for analytical method development and quality control.

Based on its molecular formula C18H33O3Na, 12-Oxystearic acid sodium salt contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 320.45 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
