Description

As a certified reference material (CRM), 66687-07-8 4-[4-[[4-(4-aminooxysulfonylanilino)phenyl]-[4-(4-aminooxysulfonylphenyl)iminocyclohexa-2,5-dien-1-ylidene]methyl]anilino]benzenesulfonic acid DTXSID50422995 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.

CATO supplies 66687-07-8 4-[4-[[4-(4-aminooxysulfonylanilino)phenyl]-[4-(4-aminooxysulfonylphenyl)iminocyclohexa-2,5-dien-1-ylidene]methyl]anilino]benzenesulfonic acid DTXSID50422995 (CAS 66687-07-8), a certified reference material (molecular formula C37H31N5O9S3, MW 785.87 g/mol) for analytical method development and quality control.

The molecular framework of 66687-07-8 4-[4-[[4-(4-aminooxysulfonylanilino)phenyl]-[4-(4-aminooxysulfonylphenyl)iminocyclohexa-2,5-dien-1-ylidene]methyl]anilino]benzenesulfonic acid DTXSID50422995 (C37H31N5O9S3) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
