1,3-Benzenedicarboxylic acid, polymer with 2,2-dimethyl-1,3-propanediol and 1,1'-methylenebis[4-isocyanatobenzene] CAS 70714-87-3

Description

1,3-Benzenedicarboxylic acid, polymer with 2,2-dimethyl-1,3-propanediol and 1,1'-methylenebis[4-isocyanatobenzene] (C15H10N2O2C8H6O4C5H12O2) contains a nitrogen-containing heterocyclic scaffold, an amide 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

1,3-Benzenedicarboxylic acid, polymer with 2,2-dimethyl-1,3-propanediol and 1,1'-methylenebis[4-isocyanatobenzene] (CAS 70714-87-3) is a high-purity analytical reference standard with the molecular formula C15H10N2O2C8H6O4C5H12O2 and a molecular weight of 520.54 g/mol.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
