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.
1,4-Benzenedicarboxylic acid, polymer with 6-hydroxy-2-naphthalenecarboxylic acid and N-(4-hydroxyphenyl)acetamide, acetate (ester) (CAS 99377-76-1) is a high-purity analytical reference standard with the molecular formula C10H11NO3C11H8O3C8H6O4 and a molecular weight of 547.52 g/mol.
1,4-Benzenedicarboxylic acid, polymer with 6-hydroxy-2-naphthalenecarboxylic acid and N-(4-hydroxyphenyl)acetamide, acetate (ester) (C10H11NO3C11H8O3C8H6O4) contains a nitrogen-containing heterocyclic scaffold, an amide 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
