Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,3-Dichloro-5-ethyl-6-methylpyrazine.
CATO supplies 2,3-Dichloro-5-ethyl-6-methylpyrazine (CAS 1461704-76-6), a certified reference material (molecular formula C7H8Cl2N2, MW 191.06 g/mol) for analytical method development and quality control.
2,3-Dichloro-5-ethyl-6-methylpyrazine (C7H8Cl2N2) contains a nitrile group, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 2,3-Dichloro-5-ethyl-6-methylpyrazine 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.
