Sodium (E)-2-((4-chloro-2-phosphonophenyl)diazenyl)-3,6-disulfonaphthalene-1,8-bis(olate) CAS 85561-96-2 chemical structure

Description

CATO manufactures Sodium (E)-2-((4-chloro-2-phosphonophenyl)diazenyl)-3,6-disulfonaphthalene-1,8-bis(olate) 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.

Sodium (E)-2-((4-chloro-2-phosphonophenyl)diazenyl)-3,6-disulfonaphthalene-1,8-bis(olate) (CAS 85561-96-2) is a high-purity analytical reference standard with the molecular formula C16H10ClN2O11PS2Na and a molecular weight of 559.79 g/mol.

The molecular framework of Sodium (E)-2-((4-chloro-2-phosphonophenyl)diazenyl)-3,6-disulfonaphthalene-1,8-bis(olate) (C16H10ClN2O11PS2Na) is characterized by a salt form, a flavonoid core, an amide group, a sulfone group, a phosphate ester group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
