Chemical Structure

Isobavachalcone CAS 20784-50-3 chemical structure

Description

Isobavachalcone (CAS 20784-50-3) is a high-purity analytical reference standard with the molecular formula C20H20O4 and a molecular weight of 324.37 g/mol.

Owing to a flavonoid core, a hydroxyl group, an ether linkage, Isobavachalcone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 324.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

As a certified reference material (CRM), Isobavachalcone meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
