Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3'-(3,4-Dichlorophenyl)-1-{[3-(trifluoromethyl)phenyl]methyl}-1,2-dihydrospiro[indole-3,2'-[1,3]thiazolidine]-2,4'-dione.
3'-(3,4-Dichlorophenyl)-1-{[3-(trifluoromethyl)phenyl]methyl}-1,2-dihydrospiro[indole-3,2'-[1,3]thiazolidine]-2,4'-dione (CAS 338418-89-6) is a high-purity analytical reference standard with the molecular formula C24H15Cl2F3N2O2S and a molecular weight of 523.35 g/mol.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 3'-(3,4-Dichlorophenyl)-1-{[3-(trifluoromethyl)phenyl]methyl}-1,2-dihydrospiro[indole-3,2'-[1,3]thiazolidine]-2,4'-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 523.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 3'-(3,4-Dichlorophenyl)-1-{[3-(trifluoromethyl)phenyl]methyl}-1,2-dihydrospiro[indole-3,2'-[1,3]thiazolidine]-2,4'-dione 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.
