Description
CATO supplies 1,3-Benzenedicarboxylic acid, polymer with 2,5-furandione, oxybis[propanol] and 1,2-propanediol (CAS 9065-68-3), a certified reference material (molecular formula C8H6O4C6H14O3C4H2O3C3H8O2, MW 474.46 g/mol) for analytical method development and quality control.
1,3-Benzenedicarboxylic acid, polymer with 2,5-furandione, oxybis[propanol] and 1,2-propanediol (C8H6O4C6H14O3C4H2O3C3H8O2) contains a flavonoid core, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
