Chemical Structure

1-Isobutyl-1H-pyrazole-4-methanamine CAS 1152576-43-6 chemical structure

Description

1-Isobutyl-1H-pyrazole-4-methanamine (CAS 1152576-43-6), molecular formula C8H15N3 and molecular weight 153.22 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1-Isobutyl-1H-pyrazole-4-methanamine (C8H15N3) 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), 1-Isobutyl-1H-pyrazole-4-methanamine 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.
