Chemical Structure

1-Methyl-1H-pyrazole-4,5-diamine CAS 45514-38-3 chemical structure

Description

As a certified reference material (CRM), 1-Methyl-1H-pyrazole-4,5-diamine 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.

CATO supplies 1-Methyl-1H-pyrazole-4,5-diamine (CAS 45514-38-3), a certified reference material (molecular formula C4H8N4, MW 112.13 g/mol) for analytical method development and quality control.

Structurally, 1-Methyl-1H-pyrazole-4,5-diamine (C4H8N4) contains a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 112.13 g/mol, it falls into the low-molecular-weight range. 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
