Chemical Structure
Description
CATO supplies 3-(Trifluoromethyl)pyrazine 1-oxide (CAS 61655-68-3), a certified reference material (molecular formula C5H3F3N2O, MW 164.09 g/mol) for analytical method development and quality control.
Owing to an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 3-(Trifluoromethyl)pyrazine 1-oxide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 164.09 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.
As a certified reference material (CRM), 3-(Trifluoromethyl)pyrazine 1-oxide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
