Chemical Structure

(2-Chlorothiazol-5-yl)methyl (4-nitrophenyl)carbamate CAS 672949-95-0 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.

(2-Chlorothiazol-5-yl)methyl (4-nitrophenyl)carbamate (CAS 672949-95-0), molecular formula C11H8ClN3O4S and molecular weight 313.72 g/mol, is a CATO reference standard with documented purity and traceability.

(2-Chlorothiazol-5-yl)methyl (4-nitrophenyl)carbamate (C11H8ClN3O4S) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), (2-Chlorothiazol-5-yl)methyl (4-nitrophenyl)carbamate 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.
