N-(4-((3,5-Dimethyl-4-nitro-1H-pyrazol-1-yl)methyl)thiazol-2-yl)-N-(3,4-dimethylphenyl)acetamide CAS 956909-87-8

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.

N-(4-((3,5-Dimethyl-4-nitro-1H-pyrazol-1-yl)methyl)thiazol-2-yl)-N-(3,4-dimethylphenyl)acetamide (CAS 956909-87-8), molecular formula C19H21N5O3S and molecular weight 399.47 g/mol, is a CATO reference standard with documented purity and traceability.

N-(4-((3,5-Dimethyl-4-nitro-1H-pyrazol-1-yl)methyl)thiazol-2-yl)-N-(3,4-dimethylphenyl)acetamide (C19H21N5O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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), N-(4-((3,5-Dimethyl-4-nitro-1H-pyrazol-1-yl)methyl)thiazol-2-yl)-N-(3,4-dimethylphenyl)acetamide 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.
