Description
CATO manufactures 6-Chloro-3,4-dihydro-2H-pyrazino[2,3-b][1,4]oxazine 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 6-Chloro-3,4-dihydro-2H-pyrazino[2,3-b][1,4]oxazine (CAS 1303587-97-4), a certified reference material (molecular formula C7H7ClN2O, MW 170.60 g/mol) for analytical method development and quality control.
Owing to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 6-Chloro-3,4-dihydro-2H-pyrazino[2,3-b][1,4]oxazine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 170.60 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.
