Chemical Structure
Description
1,4-Benzenedicarboxylic acid, 1,4-dimethyl ester, polymer with 2-methyl-1,3-propanediol and 2,2'-oxybis[ethanol] (C10H10O4C4H10O3C4H10O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
1,4-Benzenedicarboxylic acid, 1,4-dimethyl ester, polymer with 2-methyl-1,3-propanediol and 2,2'-oxybis[ethanol] (CAS 164780-85-2) is a high-purity analytical reference standard with the molecular formula C10H10O4C4H10O3C4H10O2 and a molecular weight of 390.43 g/mol.
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.
