Description
CATO manufactures 2-Ethyl-5(6)-methylpyrazine 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.
CATO supplies 2-Ethyl-5(6)-methylpyrazine (CAS 36731-41-6), a certified reference material (molecular formula C7H10N2, MW 122.17 g/mol) for analytical method development and quality control.
The molecular framework of 2-Ethyl-5(6)-methylpyrazine (C7H10N2) is characterized by a nitrile group, an aromatic ring system. 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
