Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
CATO supplies 5-[[3-Chloro-4-(2-cyclohexylethoxy)phenyl]methylene]-2,4-thiazolidinedione (CAS 1239610-72-0), a certified reference material (molecular formula C18H20ClNO3S, MW 365.87 g/mol) for analytical method development and quality control.
Structurally, 5-[[3-Chloro-4-(2-cyclohexylethoxy)phenyl]methylene]-2,4-thiazolidinedione (C18H20ClNO3S) 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 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 365.87 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
