Chemical Structure
Description
As a certified reference material (CRM), Aflatoxin G2 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.
Aflatoxin G2 (CAS 7241-98-7), molecular formula C17H14O7 and molecular weight 330.29 g/mol, is a CATO reference standard with documented purity and traceability.
Aflatoxin G2 (C17H14O7) contains a flavonoid core, a hydroxyl group, an ether linkage. 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.
