Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Hydroxy-2-(2-hydroxy-4,5-dimethylphenyl)-1H-indene-1,3(2H)-dione.

CATO supplies 2-Hydroxy-2-(2-hydroxy-4,5-dimethylphenyl)-1H-indene-1,3(2H)-dione (CAS 71321-29-4), a certified reference material (molecular formula C17H14O4, MW 282.29 g/mol) for analytical method development and quality control.

Structurally, 2-Hydroxy-2-(2-hydroxy-4,5-dimethylphenyl)-1H-indene-1,3(2H)-dione (C17H14O4) contains a flavonoid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 282.29 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 2-Hydroxy-2-(2-hydroxy-4,5-dimethylphenyl)-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.
