Chemical Structure
Description
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.
2-(4-Nitro-1h-pyrazol-1-yl)ethan-1-amine (CAS 1002033-53-5) is a high-purity analytical reference standard with the molecular formula C5H8N4O2 and a molecular weight of 156.14 g/mol.
The molecular framework of 2-(4-Nitro-1h-pyrazol-1-yl)ethan-1-amine (C5H8N4O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl 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.
CATO manufactures 2-(4-Nitro-1h-pyrazol-1-yl)ethan-1-amine 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.
