Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 148.63 g/mol gives 2-chloro-3-ethyl-pyrazine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-chloro-3-ethyl-pyrazine (CAS 63450-95-3) is a high-purity analytical reference standard with the molecular formula C6H13ClN2 and a molecular weight of 148.63 g/mol.
The molecular framework of 2-chloro-3-ethyl-pyrazine (C6H13ClN2) is characterized by 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. 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.
