Chemical Structure

4-Methyl-1-propyl-1,2-dihydro-3h-pyrazol-3-imine CAS 1174877-75-8 chemical structure

Description

4-Methyl-1-propyl-1,2-dihydro-3h-pyrazol-3-imine (CAS 1174877-75-8), molecular formula C7H13N3 and molecular weight 139.20 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-Methyl-1-propyl-1,2-dihydro-3h-pyrazol-3-imine (C7H13N3) is characterized by a nitrile group. 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), 4-Methyl-1-propyl-1,2-dihydro-3h-pyrazol-3-imine 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.
