Chemical Structure
Description
CATO supplies 2,5-dichloro-3-methyl-pyrazine (CAS 107378-41-6), a certified reference material (molecular formula C5H10Cl2N2, MW 169.05 g/mol) for analytical method development and quality control.
The molecular framework of 2,5-dichloro-3-methyl-pyrazine (C5H10Cl2N2) 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.
As a certified reference material (CRM), 2,5-dichloro-3-methyl-pyrazine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
