Chemical Structure
Description
(+)-2,3-O-Isopropylidene-D-glyceric Acid Methyl Ester (+)-Methyl 2,3-O-Isopropylidene-D-glycerate (R)-(+)-2,2-Dimethyl-1,3-dioxolane-4-carboxylic Acid Methyl Ester 52373-72-5 D2562 Methyl (R)-(+)-2,2-Dimethyl-1,3-dioxolane-4-carboxylate (CAS 52373-72-5) is a high-purity analytical reference standard with the molecular formula C7H12O4 and a molecular weight of 160.17 g/mol.
(+)-2,3-O-Isopropylidene-D-glyceric Acid Methyl Ester (+)-Methyl 2,3-O-Isopropylidene-D-glycerate (R)-(+)-2,2-Dimethyl-1,3-dioxolane-4-carboxylic Acid Methyl Ester 52373-72-5 D2562 Methyl (R)-(+)-2,2-Dimethyl-1,3-dioxolane-4-carboxylate (C7H12O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
