Description
CATO manufactures 1-(4-Chloro-2-methoxyphenyl)-2-(pyrazin-2-yl)ethanone 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.
CATO supplies 1-(4-Chloro-2-methoxyphenyl)-2-(pyrazin-2-yl)ethanone (CAS 88283-36-7), a certified reference material (molecular formula C13H11ClN2O2, MW 262.69 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 1-(4-Chloro-2-methoxyphenyl)-2-(pyrazin-2-yl)ethanone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 262.69 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
