Chemical Structure
Description
3-(chloromethyl)-2,5-dimethylpyrazine (CAS 921040-00-8), molecular formula C7H15ClN2 and molecular weight 162.66 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(chloromethyl)-2,5-dimethylpyrazine (C7H15ClN2) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 3-(chloromethyl)-2,5-dimethylpyrazine 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.
