Tetrahydropentalene-1,4(2H,5H)-dione CAS 77483-80-8

Description

The occurrence of Tetrahydropentalene-1,4(2H,5H)-dione is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Tetrahydropentalene-1,4(2H,5H)-dione (CAS 77483-80-8), molecular formula C8H10O2 and molecular weight 138.16 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Tetrahydropentalene-1,4(2H,5H)-dione (C8H10O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 138.16 g/mol, it falls into the low-molecular-weight range. 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), Tetrahydropentalene-1,4(2H,5H)-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.
