(S)-(-)-t-Butylsulfinamide (s)-(-)-2-methyl-2-propanesulfinamide (s)-(-)-t-butylmethylsulfinamide (s)-(-)-tert-butanesulfinamide (s)-(-)-2-methyl-propane-2-sulfinic acid amide (s)-tert-butanesulfinamide (s)-2-methyl-2-propanesulfinamide s-(-)-2-methyl-2-propanesulfinamide (s)-(-)-2-methyl-2-propanesulphinamide (s)-(-)-tert-butyl sulphinamide s-tert-butylsulfinamide (s)-2-methylpropane-2-sulfinamide (s)-(-)-tert-butylsulfinamide (s)-(-)-t-butyl sulfinamide 343338-28-3 (CAS 343338-28-3), molecular formula C4H11NOS and molecular weight 121.20 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (S)-(-)-t-Butylsulfinamide (s)-(-)-2-methyl-2-propanesulfinamide (s)-(-)-t-butylmethylsulfinamide (s)-(-)-tert-butanesulfinamide (s)-(-)-2-methyl-propane-2-sulfinic acid amide (s)-tert-butanesulfinamide (s)-2-methyl-2-propanesulfinamide s-(-)-2-methyl-2-propanesulfinamide (s)-(-)-2-methyl-2-propanesulphinamide (s)-(-)-tert-butyl sulphinamide s-tert-butylsulfinamide (s)-2-methylpropane-2-sulfinamide (s)-(-)-tert-butylsulfinamide (s)-(-)-t-butyl sulfinamide 343338-28-3 (C4H11NOS) contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 121.20 g/mol, it falls into the low-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.
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.
