Chemical Structure
Description
Tetrahydro-1H-cyclopenta[c]furan-1,3(3aH)-dione (CAS 5763-49-5), molecular formula C7H8O3 and molecular weight 140.14 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Tetrahydro-1H-cyclopenta[c]furan-1,3(3aH)-dione is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 140.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), Tetrahydro-1H-cyclopenta[c]furan-1,3(3aH)-dione 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.
