Chemical Structure

Difuro[3,4-b:3',4'-d]furan-1,3,5,7-tetraone CAS 28315-88-0 chemical structure

Description

As a certified reference material (CRM), Difuro[3,4-b:3',4'-d]furan-1,3,5,7-tetraone 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.

Difuro[3,4-b:3',4'-d]furan-1,3,5,7-tetraone (CAS 28315-88-0), molecular formula C8O7 and molecular weight 208.08 g/mol, is a CATO reference standard with documented purity and traceability.

Difuro[3,4-b:3',4'-d]furan-1,3,5,7-tetraone (C8O7) contains a carbohydrate-derived structure. 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.
