Chemical Structure
Description
CATO supplies (R)-2-Chloro-3-(2-methylpiperazin-1-yl)pyrazine hydrochloride (CAS 639029-52-0), a certified reference material (molecular formula C9H13ClN4HCl, MW 249.14 g/mol) for analytical method development and quality control.
(R)-2-Chloro-3-(2-methylpiperazin-1-yl)pyrazine hydrochloride (C9H13ClN4HCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 manufactures (R)-2-Chloro-3-(2-methylpiperazin-1-yl)pyrazine 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.
