Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 268.29 g/mol gives 2,4'-Diisocyanatodiphenyl Sulfide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2,4'-Diisocyanatodiphenyl Sulfide (CAS 75790-87-3), a certified reference material (molecular formula C14H8N2O2S, MW 268.29 g/mol) for analytical method development and quality control.
The molecular framework of 2,4'-Diisocyanatodiphenyl Sulfide (C14H8N2O2S) 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 its high hydrophobicity (logP), 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.
CATO manufactures 2,4'-Diisocyanatodiphenyl Sulfide 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.
