Chemical Structure
Description
(5Z)-3-[(4-tert-Butylphenyl)methyl]-5-[(4-tert-butylphenyl)methylidene]-1,3-thiazolidine-2,4-dione (CAS 299417-35-9) is a high-purity analytical reference standard with the molecular formula C25H29NO2S and a molecular weight of 407.57 g/mol.
The molecular framework of (5Z)-3-[(4-tert-Butylphenyl)methyl]-5-[(4-tert-butylphenyl)methylidene]-1,3-thiazolidine-2,4-dione (C25H29NO2S) 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 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.
As a certified reference material (CRM), (5Z)-3-[(4-tert-Butylphenyl)methyl]-5-[(4-tert-butylphenyl)methylidene]-1,3-thiazolidine-2,4-dione 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.
