Chemical Structure

2,5-Dichlorobenzophenone CAS 16611-67-9 chemical structure

Description

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

CATO supplies 2,5-Dichlorobenzophenone (CAS 16611-67-9), a certified reference material (molecular formula C13H8Cl2O, MW 251.11 g/mol) for analytical method development and quality control.

Owing to a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 2,5-Dichlorobenzophenone is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 251.11 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
