4-(4-Chlorophenyl)-4-oxobutanenitrile CAS 40394-87-4

Description

The occurrence of 4-(4-Chlorophenyl)-4-oxobutanenitrile is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-(4-Chlorophenyl)-4-oxobutanenitrile (CAS 40394-87-4) is a high-purity analytical reference standard with the molecular formula C10H8ClNO and a molecular weight of 193.63 g/mol.

Structurally, 4-(4-Chlorophenyl)-4-oxobutanenitrile (C10H8ClNO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 193.63 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).

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.
