Chemical Structure
Description
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.
CATO supplies 1,3-Benzenedicarboxylic acid, polymer with 2,2-bis(hydroxymethyl)-1,3-propanediol, 2,5-furandione, 1,3-isobenzofurandione and 1,2-propanediol (CAS 65605-80-3), a certified reference material (molecular formula C8H6O4C8H4O3C5H12O4C4H2O3C3H8O2, MW 624.55 g/mol) for analytical method development and quality control.
1,3-Benzenedicarboxylic acid, polymer with 2,2-bis(hydroxymethyl)-1,3-propanediol, 2,5-furandione, 1,3-isobenzofurandione and 1,2-propanediol (C8H6O4C8H4O3C5H12O4C4H2O3C3H8O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
