Chemical Structure
Description
The occurrence of 3,3-Dimethyl-4-(propan-2-ylidene)oxetan-2-one 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.
3,3-Dimethyl-4-(propan-2-ylidene)oxetan-2-one (CAS 3173-79-3), molecular formula C8H12O2 and molecular weight 140.18 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3,3-Dimethyl-4-(propan-2-ylidene)oxetan-2-one (C8H12O2) 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 140.18 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.
