Chemical Structure

Sodium naphthalene-1,5-disulfonate dihydrate CAS 76758-30-0 chemical structure

Description

CATO supplies Sodium naphthalene-1,5-disulfonate dihydrate (CAS 76758-30-0), a certified reference material (molecular formula C10H6O6S2NaH2O, MW 327.28 g/mol) for analytical method development and quality control.

Structurally, Sodium naphthalene-1,5-disulfonate dihydrate (C10H6O6S2NaH2O) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 327.28 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures Sodium naphthalene-1,5-disulfonate dihydrate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
