Description
CATO supplies 5-Iodo-3-methylpyrazin-2-amine (CAS 91416-90-9), a certified reference material (molecular formula C5H6IN3, MW 235.03 g/mol) for analytical method development and quality control.
Owing to a nitrile group, iodine substitution, 5-Iodo-3-methylpyrazin-2-amine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 235.03 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 5-Iodo-3-methylpyrazin-2-amine 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.
