Chemical Structure

DIFFRACTAIC ACID CAS 436-32-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 374.38 g/mol gives DIFFRACTAIC ACID distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies DIFFRACTAIC ACID (CAS 436-32-8), a certified reference material (molecular formula C20H22O7, MW 374.38 g/mol) for analytical method development and quality control.

Owing to a flavonoid core, a hydroxyl group, an ether linkage, DIFFRACTAIC ACID is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 374.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), DIFFRACTAIC ACID 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.
