Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-[(2-Chlorophenyl)methyl]-3'-(3,4-dichlorophenyl)-1,2-dihydrospiro[indole-3,2'-[1,3]thiazolidine]-2,4'-dione.
CATO supplies 1-[(2-Chlorophenyl)methyl]-3'-(3,4-dichlorophenyl)-1,2-dihydrospiro[indole-3,2'-[1,3]thiazolidine]-2,4'-dione (CAS 338406-11-4), a certified reference material (molecular formula C23H15Cl3N2O2S, MW 489.80 g/mol) for analytical method development and quality control.
Structurally, 1-[(2-Chlorophenyl)methyl]-3'-(3,4-dichlorophenyl)-1,2-dihydrospiro[indole-3,2'-[1,3]thiazolidine]-2,4'-dione (C23H15Cl3N2O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 489.80 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), 1-[(2-Chlorophenyl)methyl]-3'-(3,4-dichlorophenyl)-1,2-dihydrospiro[indole-3,2'-[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.
