Chemical Structure

7-chloro-2-ethyl-4,4-dioxo-1,2,3-trihydro-4-thiaquinazoline-6-sulfonamide CAS 1824-58-4 chemical structure

Description

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.

CATO supplies 7-chloro-2-ethyl-4,4-dioxo-1,2,3-trihydro-4-thiaquinazoline-6-sulfonamide (CAS 1824-58-4), a certified reference material (molecular formula C9H12ClN3O4S2, MW 325.79 g/mol) for analytical method development and quality control.

7-chloro-2-ethyl-4,4-dioxo-1,2,3-trihydro-4-thiaquinazoline-6-sulfonamide (C9H12ClN3O4S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

As a certified reference material (CRM), 7-chloro-2-ethyl-4,4-dioxo-1,2,3-trihydro-4-thiaquinazoline-6-sulfonamide 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.
