Chemical Structure

Oleanolic Acid-d CAS 946530-77-4 chemical structure

Description

CATO supplies Oleanolic Acid-d (CAS 946530-77-4), a certified reference material (molecular formula C30H45D3O3, MW 459.72 g/mol) for analytical method development and quality control.

Based on its molecular formula C30H45D3O3, Oleanolic Acid-d contains deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 459.72 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

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.
