Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 203.07 g/mol gives 2,2-Dichloro-1-(4-methylphenyl)ethanone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2,2-Dichloro-1-(4-methylphenyl)ethanone (CAS 4974-59-8), a certified reference material (molecular formula C9H8Cl2O, MW 203.07 g/mol) for analytical method development and quality control.
Owing to a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 2,2-Dichloro-1-(4-methylphenyl)ethanone is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 203.07 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
