3513-81-3 2-Methylenepropane-1,3-diol 1,3-Propanediol, 2-methylene- EINECS 222-516-7 2-Methylene-1,3-propanediol (CAS 3513-81-3) is a high-purity analytical reference standard with the molecular formula C4H8O2 and a molecular weight of 88.11 g/mol.
3513-81-3 2-Methylenepropane-1,3-diol 1,3-Propanediol, 2-methylene- EINECS 222-516-7 2-Methylene-1,3-propanediol (C4H8O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.
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.
