3-(5-Bromothiophen-2-yl)-1,4-dimethyl-1h-pyrazol-5-amine (CAS 1152663-33-6), molecular formula C9H10BrN3S and molecular weight 272.16 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-(5-Bromothiophen-2-yl)-1,4-dimethyl-1h-pyrazol-5-amine (C9H10BrN3S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 3-(5-Bromothiophen-2-yl)-1,4-dimethyl-1h-pyrazol-5-amine 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.
