General description

5-Chloro-2-methylphenyl isocyanate, also known as 4-chloro-2-isocyanato-1-methylbenzene, is an organic building block containing an isocyanate group. Its Raman spectra, infrared spectra, ab initio and density functional theory (DFT) calculations have been reported.[1]

Application

5-Chloro-2-methylphenyl isocyanate may be used in the synthesis of:
  • N-(5-chloro-2-methyphenyl)-N′-(1-methylethyl)-thiourea[2]
  • N-(5-chloro-2-methyphenyl)-N′-(1-methylethyl)-urea[2]
  • 5-chloro-2-methylphenylcarbamoylated cyclodextrin (CD) chiral stationary phase (CSP)[3]

In this work, two cyclodextrin (CD) chiral stationary phases (CSPs) have been developed by clicking per-4-chloro-3-methylphenylcarbamoylated mono-6(A)-azido-β-CD (CSP1) and per-5-chloro-2-methylphenylcarbamoylated mono-6(A)-azido-β-CD (CSP2) onto alkynylated silica support. The enantioslectivies of the as-obtained new CSPs have been evaluated using 29 model racemates

Treatment of atherosclerotic disease often focuses on reducing plasma LDL-cholesterol or increasing plasma HDL-cholesterol. We examined in vitro the effects on HDL receptor [scavenger receptor class B type I (SR-BI)] activity of three classes of clinical and experimental plasma HDL-cholesterol-elevating
