Chemical Structure

2,4-Diphenylbenzo[h]chromen-1-ium tetrafluoroborate CAS 35096-76-5 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,4-Diphenylbenzo[h]chromen-1-ium tetrafluoroborate.

2,4-Diphenylbenzo[h]chromen-1-ium tetrafluoroborate (CAS 35096-76-5), molecular formula C25H17OBF4 and molecular weight 420.21 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, a hydroxyl group, an ether linkage, fluorine substitution, 2,4-Diphenylbenzo[h]chromen-1-ium tetrafluoroborate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 420.21 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), 2,4-Diphenylbenzo[h]chromen-1-ium tetrafluoroborate 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.
