7-Hydroxyflavone CAS 6665-86-7 chemical structure

Description

CATO supplies 7-Hydroxyflavone (CAS 6665-86-7), a certified reference material (molecular formula C15H10O3, MW 238.24 g/mol) for analytical method development and quality control.

Structurally, 7-Hydroxyflavone (C15H10O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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 238.24 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
