CATO supplies (5E)-3-Ethyl-5-{[5-nitro-2-(phenylsulfanyl)phenyl]methylidene}-2-sulfanylidene-1,3-thiazolidin-4-one (CAS 329079-73-4), a certified reference material (molecular formula C18H14N2O3S3, MW 402.51 g/mol) for analytical method development and quality control.
The molecular framework of (5E)-3-Ethyl-5-{[5-nitro-2-(phenylsulfanyl)phenyl]methylidene}-2-sulfanylidene-1,3-thiazolidin-4-one (C18H14N2O3S3) is characterized by a steroid core, 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.
