Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(2-Chloro-4-methylphenyl)ethanone, 97%.
1-(2-Chloro-4-methylphenyl)ethanone, 97% (CAS 90649-68-6), molecular formula C9H9ClO and molecular weight 168.62 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-(2-Chloro-4-methylphenyl)ethanone, 97% (C9H9ClO) contains a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 168.62 g/mol, it falls into the medium-molecular-weight range. 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.
