Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 183.04 g/mol gives 6-chloropyrazine-2-carbonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 6-chloropyrazine-2-carbonyl chloride (CAS 148673-71-6), a certified reference material (molecular formula C5H8Cl2N2O, MW 183.04 g/mol) for analytical method development and quality control.
Owing to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 6-chloropyrazine-2-carbonyl chloride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 183.04 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 6-chloropyrazine-2-carbonyl chloride 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.
