Chemical Structure
Description
The occurrence of 3-O-Acetyl-11-hydroxy-beta-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.
3-O-Acetyl-11-hydroxy-beta-boswellic acid (CAS 146019-25-2) is a high-purity analytical reference standard with the molecular formula C32H50O5 and a molecular weight of 514.74 g/mol.
3-O-Acetyl-11-hydroxy-beta-boswellic acid (C32H50O5) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
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.
