Chemical Structure

1,5-Dimethyl-1H-pyrazol-3-amine dihydrochloride CAS 1432026-78-2 chemical structure

Description

1,5-Dimethyl-1H-pyrazol-3-amine dihydrochloride (CAS 1432026-78-2), molecular formula C5H9N3HCl and molecular weight 147.61 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1,5-Dimethyl-1H-pyrazol-3-amine dihydrochloride (C5H9N3HCl) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), 1,5-Dimethyl-1H-pyrazol-3-amine 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.
