Tuberculostearic Acid CAS 542-47-2 chemical structure

Description

CATO supplies Tuberculostearic Acid (CAS 542-47-2), a certified reference material (molecular formula C19H38O2, MW 298.50 g/mol) for analytical method development and quality control.

Based on its molecular formula C19H38O2, Tuberculostearic Acid 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 298.50 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.

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

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.
