4-(2-Chloropropanoyl)-7-(trifluoromethyl)-1,2,3,4-tetrahydroquinoxalin-2-one CAS 949835-70-5 chemical structure

Description

The occurrence of 4-(2-Chloropropanoyl)-7-(trifluoromethyl)-1,2,3,4-tetrahydroquinoxalin-2-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4-(2-Chloropropanoyl)-7-(trifluoromethyl)-1,2,3,4-tetrahydroquinoxalin-2-one (CAS 949835-70-5), a certified reference material (molecular formula C12H10ClF3N2O2, MW 306.67 g/mol) for analytical method development and quality control.

Structurally, 4-(2-Chloropropanoyl)-7-(trifluoromethyl)-1,2,3,4-tetrahydroquinoxalin-2-one (C12H10ClF3N2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/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 306.67 g/mol, it falls into the moderately-high-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.

As a certified reference material (CRM), 4-(2-Chloropropanoyl)-7-(trifluoromethyl)-1,2,3,4-tetrahydroquinoxalin-2-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories.
