Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 285.17 g/mol gives 2-Chloro-3-(piperazin-1-yl)quinoxaline hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Chloro-3-(piperazin-1-yl)quinoxaline hydrochloride (CAS 55686-36-7), molecular formula C12H13ClN4HCl and molecular weight 285.17 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Chloro-3-(piperazin-1-yl)quinoxaline hydrochloride (C12H13ClN4HCl) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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-Chloro-3-(piperazin-1-yl)quinoxaline hydrochloride 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.
