Chemical Structure

3-O-Acetyl 9,11-dehydro β-boswellic acid CAS 122651-20-1 chemical structure

Description

The occurrence of 3-O-Acetyl 9,11-dehydro β-boswellic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3-O-Acetyl 9,11-dehydro β-boswellic acid (CAS 122651-20-1), a certified reference material (molecular formula C32H48O4, MW 496.72 g/mol) for analytical method development and quality control.

Structurally, 3-O-Acetyl 9,11-dehydro β-boswellic acid (C32H48O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 496.72 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
