Chemical Structure
Description
The occurrence of 1H-pyrazole-3,4-diamine sulfate is closely related to an amide group, a sulfone group, a carboxylic acid group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1H-pyrazole-3,4-diamine sulfate (CAS 16258-80-3), a certified reference material (molecular formula C3H6N4H2O4S, MW 196.18 g/mol) for analytical method development and quality control.
The molecular framework of 1H-pyrazole-3,4-diamine sulfate (C3H6N4H2O4S) is characterized by an amide group, a sulfone group, a carboxylic acid group, an ether linkage. 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. 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.
CATO manufactures 1H-pyrazole-3,4-diamine sulfate 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.
