Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 182.65 g/mol gives 1-(3-Chloro-2-methylphenyl)propan-2-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1-(3-Chloro-2-methylphenyl)propan-2-one (CAS 118988-89-9), a certified reference material (molecular formula C10H11ClO, MW 182.65 g/mol) for analytical method development and quality control.
Owing to a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 1-(3-Chloro-2-methylphenyl)propan-2-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 182.65 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
