Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Chloro-1-(4-chloro-2-methylphenyl)ethan-1-one.
2-Chloro-1-(4-chloro-2-methylphenyl)ethan-1-one (CAS 60988-75-2), molecular formula C9H8Cl2O and molecular weight 203.07 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-Chloro-1-(4-chloro-2-methylphenyl)ethan-1-one (C9H8Cl2O) 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 203.07 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.
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.
