Chemical Structure

Triamterene RC 2 (Sodium Salt) CAS 73756-87-3 chemical structure

Description

Triamterene RC 2 (Sodium Salt) (C12H10N7NaO4) 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).

CATO supplies Triamterene RC 2 (Sodium Salt) (CAS 73756-87-3), a certified reference material (molecular formula C12H10N7NaO4, MW 371.31 g/mol) for analytical method development and quality control.

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.
