Sodium 4-((4-((4-((4-sulfonatophenyl)amino)phenyl)(4-((4-sulfophenyl)amino)phenyl)methylene)cyclohexa-2,5-dien-1-ylidene)amino)benzenesulfonate (CAS 6415-98-1), molecular formula C37H27N3O9S3Na and molecular weight 776.80 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Sodium 4-((4-((4-((4-sulfonatophenyl)amino)phenyl)(4-((4-sulfophenyl)amino)phenyl)methylene)cyclohexa-2,5-dien-1-ylidene)amino)benzenesulfonate is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 776.80 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), Sodium 4-((4-((4-((4-sulfonatophenyl)amino)phenyl)(4-((4-sulfophenyl)amino)phenyl)methylene)cyclohexa-2,5-dien-1-ylidene)amino)benzenesulfonate 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.
