Chemical Structure

1-Ethyl-3-methyl-1H-pyrazole-4,5-diamine dihydrochloride CAS 221110-59-4 chemical structure

Description

As a certified reference material (CRM), 1-Ethyl-3-methyl-1H-pyrazole-4,5-diamine dihydrochloride 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.

1-Ethyl-3-methyl-1H-pyrazole-4,5-diamine dihydrochloride (CAS 221110-59-4), molecular formula C6H12N4HCl and molecular weight 176.65 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1-Ethyl-3-methyl-1H-pyrazole-4,5-diamine dihydrochloride (C6H12N4HCl) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
