Chemical Structure
Description
The occurrence of 2,7-Naphthalenedicarboxylic acid, 97% is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2,7-Naphthalenedicarboxylic acid, 97% (CAS 2089-89-6), a certified reference material (molecular formula C12H8O4, MW 216.19 g/mol) for analytical method development and quality control.
Based on its molecular formula C12H8O4, 2,7-Naphthalenedicarboxylic acid, 97% contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 216.19 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
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.
