Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-(2H-Tetrazol-5-yl)-2-naphthoic acid.
CATO supplies 6-(2H-Tetrazol-5-yl)-2-naphthoic acid (CAS 2045896-88-4), a certified reference material (molecular formula C12H8N4O2, MW 240.22 g/mol) for analytical method development and quality control.
6-(2H-Tetrazol-5-yl)-2-naphthoic acid (C12H8N4O2) contains an amino-acid-derived structure, 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).
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.
