Chemical Structure
Description
Sodium 8-amino-4-bromonaphthalene-1-sulfonate (CAS 223103-14-8), molecular formula C10H7BrNNaO3S and molecular weight 324.13 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Sodium 8-amino-4-bromonaphthalene-1-sulfonate (C10H7BrNNaO3S) is characterized by a salt form, a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 8-amino-4-bromonaphthalene-1-sulfonate 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.
