SB-332235 (6-Chloro-3-[3-(2,3-dichlorophenyl)ureido]-2-hydroxybenzenesulfonamide) (CAS 276702-15-9), molecular formula C13H10Cl3N3O4S and molecular weight 410.66 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, SB-332235 (6-Chloro-3-[3-(2,3-dichlorophenyl)ureido]-2-hydroxybenzenesulfonamide) (C13H10Cl3N3O4S) contains a nitrogen-containing heterocyclic scaffold, 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 410.66 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
