Chemical Structure

2,4-Dioxo-1,2,3,4-tetrahydroquinazoline-6-sulfonyl chloride CAS 56044-12-3 chemical structure

Description

The occurrence of 2,4-Dioxo-1,2,3,4-tetrahydroquinazoline-6-sulfonyl chloride is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2,4-Dioxo-1,2,3,4-tetrahydroquinazoline-6-sulfonyl chloride (CAS 56044-12-3), molecular formula C8H5ClN2O4S and molecular weight 260.65 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2,4-Dioxo-1,2,3,4-tetrahydroquinazoline-6-sulfonyl chloride (C8H5ClN2O4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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 260.65 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).
