Chemical Structure

1H-pyrazol-1-amine CAS 3994-46-5 chemical structure

Description

The occurrence of 1H-pyrazol-1-amine is closely related to a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1H-pyrazol-1-amine (CAS 3994-46-5), molecular formula C3H5N3 and molecular weight 83.09 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrile group, 1H-pyrazol-1-amine is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 83.09 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), 1H-pyrazol-1-amine 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.
