Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 170.64 g/mol gives 2-(tert-Butyl)-3-chloropyrazine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-(tert-Butyl)-3-chloropyrazine (CAS 1209459-61-9), a certified reference material (molecular formula C8H11ClN2, MW 170.64 g/mol) for analytical method development and quality control.
The molecular framework of 2-(tert-Butyl)-3-chloropyrazine (C8H11ClN2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 2-(tert-Butyl)-3-chloropyrazine 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.
