Chemical Structure
Description
2-Chloro-1-(4-((4-nitrophenyl)sulfonyl)piperazin-1-yl)ethan-1-one (CAS 1087784-07-3), molecular formula C12H14ClN3O5S and molecular weight 347.77 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-Chloro-1-(4-((4-nitrophenyl)sulfonyl)piperazin-1-yl)ethan-1-one (C12H14ClN3O5S) 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 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 347.77 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).
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), 2-Chloro-1-(4-((4-nitrophenyl)sulfonyl)piperazin-1-yl)ethan-1-one 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.
