Chemical Structure
Description
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 supplies 6226-76-2 Crocein scarlet 7B sodium 7-hydroxy-8-((E)-(2-methyl-4-((E)-(2-methyl-4-sulfonatophenyl)diazenyl)phenyl)diazenyl)naphthalene-1-sulfonate (CAS 6226-76-2), a certified reference material (molecular formula C24H42N4O7S2Na, MW 585.73 g/mol) for analytical method development and quality control.
The molecular framework of 6226-76-2 Crocein scarlet 7B sodium 7-hydroxy-8-((E)-(2-methyl-4-((E)-(2-methyl-4-sulfonatophenyl)diazenyl)phenyl)diazenyl)naphthalene-1-sulfonate (C24H42N4O7S2Na) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
CATO manufactures 6226-76-2 Crocein scarlet 7B sodium 7-hydroxy-8-((E)-(2-methyl-4-((E)-(2-methyl-4-sulfonatophenyl)diazenyl)phenyl)diazenyl)naphthalene-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.
