2-isothiocyanato-propane 2253-73-8 5-Fluoro-2-chlorobenzoic acid Isopropyl isothiocyanate ipncs isopropyl isothiocya isopropyl isothiocyanate, 95+% isothiocyanato-2-propane isothiocyanic acid isopropyl ester propane, 2-isothiocyanato- (CAS 2253-73-8), molecular formula C4H7NS and molecular weight 101.17 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C4H7NS, 2-isothiocyanato-propane 2253-73-8 5-Fluoro-2-chlorobenzoic acid Isopropyl isothiocyanate ipncs isopropyl isothiocya isopropyl isothiocyanate, 95+% isothiocyanato-2-propane isothiocyanic acid isopropyl ester propane, 2-isothiocyanato- contains a nitrile group, sulfur-containing functionality; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 101.17 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
