Chemical Structure
Description
The occurrence of 3,4,5-Trimethyl-2(5H)-furanone is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3,4,5-Trimethyl-2(5H)-furanone (CAS 33488-51-6), a certified reference material (molecular formula C7H10O2, MW 126.15 g/mol) for analytical method development and quality control.
Structurally, 3,4,5-Trimethyl-2(5H)-furanone (C7H10O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 126.15 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), 3,4,5-Trimethyl-2(5H)-furanone 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.
