CATO supplies 2,2,5-Trimethyl-1,3-dioxane-4,6-dione 3709-18-0 Methyl Meldrum inverted exclamation mark s acid Methylmalonic acid cyclic isopropylidene ester cycl-Isopropylidene methylmalonate (CAS 3709-18-0), a certified reference material (molecular formula C7H10O4, MW 158.15 g/mol) for analytical method development and quality control.
Structurally, 2,2,5-Trimethyl-1,3-dioxane-4,6-dione 3709-18-0 Methyl Meldrum inverted exclamation mark s acid Methylmalonic acid cyclic isopropylidene ester cycl-Isopropylidene methylmalonate (C7H10O4) 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 158.15 g/mol, it falls into the medium-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).
As a certified reference material (CRM), 2,2,5-Trimethyl-1,3-dioxane-4,6-dione 3709-18-0 Methyl Meldrum inverted exclamation mark s acid Methylmalonic acid cyclic isopropylidene ester cycl-Isopropylidene methylmalonate 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.
