622-58-2 4-tolyl isocyanate TMI para-tolyl monoisocyanate p-TMI 4-Tol-NCO Isocyanic acid, p-tolyl ester p-tolylmonoisocyanate PTI 4-Isocyanatotoluene 4-Methylphenyl isocyanate p-Isocyanatotoluene p-Methylphenyl isocyanate p-Toluene isocyanate p-Tolyl isocyanate 1-isocyanato-4-methylbenzene CHEBI:53732 CAS 622-58-2

Description

Based on its molecular formula C8H13NO, 622-58-2 4-tolyl isocyanate TMI para-tolyl monoisocyanate p-TMI 4-Tol-NCO Isocyanic acid, p-tolyl ester p-tolylmonoisocyanate PTI 4-Isocyanatotoluene 4-Methylphenyl isocyanate p-Isocyanatotoluene p-Methylphenyl isocyanate p-Toluene isocyanate p-Tolyl isocyanate 1-isocyanato-4-methylbenzene CHEBI:53732 contains an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 139.19 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

622-58-2 4-tolyl isocyanate TMI para-tolyl monoisocyanate p-TMI 4-Tol-NCO Isocyanic acid, p-tolyl ester p-tolylmonoisocyanate PTI 4-Isocyanatotoluene 4-Methylphenyl isocyanate p-Isocyanatotoluene p-Methylphenyl isocyanate p-Toluene isocyanate p-Tolyl isocyanate 1-isocyanato-4-methylbenzene CHEBI:53732 (CAS 622-58-2) is a high-purity analytical reference standard with the molecular formula C8H13NO and a molecular weight of 139.19 g/mol.

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.
