Chemical Structure

4,4,5,7-Tetramethylchroman-2-one CAS 40662-14-4 chemical structure

Description

4,4,5,7-Tetramethylchroman-2-one (CAS 40662-14-4) is a high-purity analytical reference standard with the molecular formula C13H16O2 and a molecular weight of 204.26 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 4,4,5,7-Tetramethylchroman-2-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 204.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), 4,4,5,7-Tetramethylchroman-2-one 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.
