Chemical Structure
Description
2-(4-Chloro-5-methyl-1H-pyrazol-1-yl)ethan-1-amine (CAS 1006468-92-3), molecular formula C6H10ClN3 and molecular weight 159.62 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(4-Chloro-5-methyl-1H-pyrazol-1-yl)ethan-1-amine (C6H10ClN3) is characterized by a nitrile group, chlorine 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), 2-(4-Chloro-5-methyl-1H-pyrazol-1-yl)ethan-1-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.
