Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 7-Hydroxy-1,3,6-naphthalenetrisulfonic Acid Trisodium Salt (CAS 53683-45-7), a certified reference material (molecular formula C10H5O10S3Na, MW 404.31 g/mol) for analytical method development and quality control.
Based on its molecular formula C10H5O10S3Na, 7-Hydroxy-1,3,6-naphthalenetrisulfonic Acid Trisodium Salt contains a carbohydrate-derived structure, a sulfone group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 404.31 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).
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.
