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 n-(4-Chloro-3-nitrophenyl)-2-((1-methyl-1h-imidazol-2-yl)thio)acetamide (CAS 306730-71-2), a certified reference material (molecular formula C12H11ClN4O3S, MW 326.76 g/mol) for analytical method development and quality control.
Structurally, n-(4-Chloro-3-nitrophenyl)-2-((1-methyl-1h-imidazol-2-yl)thio)acetamide (C12H11ClN4O3S) 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 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 326.76 g/mol, it falls into the moderately-high-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).
As a certified reference material (CRM), n-(4-Chloro-3-nitrophenyl)-2-((1-methyl-1h-imidazol-2-yl)thio)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.
