2-(2,3,5,6-Tetramethylbenzylidene)-1H-indene-1,3(2H)-dione CAS 54689-99-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(2,3,5,6-Tetramethylbenzylidene)-1H-indene-1,3(2H)-dione.

CATO supplies 2-(2,3,5,6-Tetramethylbenzylidene)-1H-indene-1,3(2H)-dione (CAS 54689-99-5), a certified reference material (molecular formula C21H24O4, MW 340.41 g/mol) for analytical method development and quality control.

Owing to a flavonoid core, a hydroxyl group, an ether linkage, 2-(2,3,5,6-Tetramethylbenzylidene)-1H-indene-1,3(2H)-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 340.41 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-(2,3,5,6-Tetramethylbenzylidene)-1H-indene-1,3(2H)-dione 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.
