Chemical Structure

Sodium 4-Amino-1-naphthalenesulfonate Tetrahydrate CAS 130-13-2 chemical structure

Description

As a certified reference material (CRM), Sodium 4-Amino-1-naphthalenesulfonate Tetrahydrate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

Sodium 4-Amino-1-naphthalenesulfonate Tetrahydrate (CAS 130-13-2), molecular formula C10H8NO3SNaH2O and molecular weight 263.24 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C10H8NO3SNaH2O, Sodium 4-Amino-1-naphthalenesulfonate Tetrahydrate contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 263.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
