Chemical Structure

1-[(dimethyl-1,2-oxazol-4-yl)sulfonyl]piperazine hydrochloride CAS 1803583-13-2 chemical structure

Description

The occurrence of 1-[(dimethyl-1,2-oxazol-4-yl)sulfonyl]piperazine hydrochloride is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-[(dimethyl-1,2-oxazol-4-yl)sulfonyl]piperazine hydrochloride (CAS 1803583-13-2) is a high-purity analytical reference standard with the molecular formula C9H15N3O3SHCl and a molecular weight of 281.75 g/mol.

1-[(dimethyl-1,2-oxazol-4-yl)sulfonyl]piperazine hydrochloride (C9H15N3O3SHCl) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 1-[(dimethyl-1,2-oxazol-4-yl)sulfonyl]piperazine hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
