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 Sodium 6-((4-(2-iodoacetamido)phenyl)amino)naphthalene-2-sulfonate.
Sodium 6-((4-(2-iodoacetamido)phenyl)amino)naphthalene-2-sulfonate (CAS 143756-46-1) is a high-purity analytical reference standard with the molecular formula C18H14IN2O4SNa and a molecular weight of 504.27 g/mol.
Sodium 6-((4-(2-iodoacetamido)phenyl)amino)naphthalene-2-sulfonate (C18H14IN2O4SNa) contains a salt form, a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, iodine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
