Chemical Structure
Description
CATO supplies 3α-acetyloxylanosta-8,24-dien-21-oic acid (CAS 174391-64-1), a certified reference material (molecular formula C32H50O4, MW 498.74 g/mol) for analytical method development and quality control.
Based on its molecular formula C32H50O4, 3α-acetyloxylanosta-8,24-dien-21-oic acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 498.74 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.
