Description

The occurrence of 8-Amino-1,6-naphthalenedisulfonic Acid Disodium SaltDISCONTINUED is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

8-Amino-1,6-naphthalenedisulfonic Acid Disodium SaltDISCONTINUED (CAS 6967-48-2), molecular formula C10H7NO6S2Na and molecular weight 324.28 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 8-Amino-1,6-naphthalenedisulfonic Acid Disodium SaltDISCONTINUED (C10H7NO6S2Na) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 324.28 g/mol, it falls into the moderately-high-molecular-weight range. 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.
