Chemical Structure

4-Amino-1-methylpyrazole CAS 69843-13-6 chemical structure

Description

4-Amino-1-methylpyrazole (CAS 69843-13-6), molecular formula C4H7N3 and molecular weight 97.12 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrile group, 4-Amino-1-methylpyrazole is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 97.12 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), 4-Amino-1-methylpyrazole 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.
