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.
CATO supplies 2-(3-(Pyrazin-2-yl)-1H-pyrazol-1-yl)ethan-1-amine (CAS 2092548-70-2), a certified reference material (molecular formula C9H11N5, MW 189.22 g/mol) for analytical method development and quality control.
The molecular framework of 2-(3-(Pyrazin-2-yl)-1H-pyrazol-1-yl)ethan-1-amine (C9H11N5) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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-(3-(Pyrazin-2-yl)-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.
