Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Pyrazin-2-ylmethanamineoxalate.
CATO supplies Pyrazin-2-ylmethanamineoxalate (CAS 1170817-91-0), a certified reference material (molecular formula C5H7N3C2H2O4, MW 199.17 g/mol) for analytical method development and quality control.
Pyrazin-2-ylmethanamineoxalate (C5H7N3C2H2O4) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), Pyrazin-2-ylmethanamineoxalate 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.
