Chemical Structure

4-(4-Chlorophenyl)but-3-en-2-one CAS 30626-03-0 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.

4-(4-Chlorophenyl)but-3-en-2-one (CAS 30626-03-0), molecular formula C10H9ClO and molecular weight 180.63 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4-(4-Chlorophenyl)but-3-en-2-one (C10H9ClO) contains a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 180.63 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).

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.
