Chemical Structure
Description
The occurrence of 1H-Pyrazole-3,4-diamine is closely related to a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1H-Pyrazole-3,4-diamine (CAS 16461-98-6) is a high-purity analytical reference standard with the molecular formula C3H6N4 and a molecular weight of 98.11 g/mol.
1H-Pyrazole-3,4-diamine (C3H6N4) contains a nitrile group. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures 1H-Pyrazole-3,4-diamine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
