chloroform (trichloromethane; CHCl3). CAS number 67-66-3 A colorless liquid with a high vapor pressure and a characteristic odor. It has been used as an anesthetic, but its use has been discontinued because it is hepatotoxic and nephrotoxic, and may cause cardiac arrhythmias leading to death....
Nitration of phenol in reversed micelle systems with dilute nitric acid, CHCl3/CTAC/H2O (2.0 mol dm− 3 HNO3 in the 1.0% (v/v) H2O phase), was performed at 35 °C to obtain 2- and 4-nitrophenols, where CTAC represents cetyltrimethylammonium chloride. In similar CTAC and ...
Purify the acid by fractional crystallisation from its melt, then crystallise it repeatedly from dry *benzene and store it over conc H2SO4 in a vacuum desiccator. It can also be crystallised from CHCl3 or cyclohexane, and dried over P2O5 or Mg(ClO4)2 in a vacuum desiccator. Trichloroacetic ...
UV–Vis (CHCl3) λmax: 416, 516, 554, 592 and 649 nm. IR (ν, cm−1): 3423 ν(O−H,N–H), 1469 ν(C=N), 808, ν(macrocycle ring’s N–H out of plane bending vibration), 1599 ν(N−H bending) ,1228 ν(C−N), 1001 ν(Co−N). Synthesis of Cobalt (II) co...
The high m.pt. polyesters are partially soluble in polar solvents, e.g. CHCl3, N-methyl pyrrolidone, dimethyl-sulphoxide. The lower m.pt polyesters are thermoplastic and may be extruded or injection moulded. The higher m.pt polyesters may be shaped in the cold, e.g. pressing or rolling,...
The pellets were resuspended in 0.665 ml of H buffer (100 mM HEPES, 150 mM NaCl, 2 mM MgCl2, 1% BSA, pH 7.0) and permeabilized by vortexing for 1 min after the addition of 0.055 ml each of CHCl3 and 0.1% SDS. The reaction was started by adding 0.125 ml of 40 mM stock solution ...

Branched fatty acid (FA) esters of hydroxy FAs (HFAs; FAHFAs) are recently discovered lipids that are conserved from yeast to mammals1,2. A subfamily, palmitic acid esters of hydroxy stearic acids (PAHSAs), are anti-inflammatory and anti-diabetic1,3. Humans and mice with insulin resistance...
Abstraction of the sulfonamide N–H or phenol O–H proton is the prerequisite to achieve C-nitration of these substrates. In contrast, we disclose our findings to report a direct nitration approach of electron-rich arenes under mild conditions using tert-butyl nitrite (TBN) as nitro source (...
