Ketoconazole is soluble in methanol, ethanol, and chloroform; slightly soluble in dilute acids; and barely soluble in water. The imidazole antimycotic ketoconazole was first synthesized at Janssen Pharmaceuticals. Trade Names Candoral (Ache), Cet- ´ onax (Cilag), Fitonal (Disprovent), Funga...
After rotary evaporation of the mixture, to remove traces of EZ-Link Pentylamine-Biotin azeotrope with toluene (2 × 5 mL) and the residue was dissolved in methanol and added oxalic acid dehydrate. After evaporation, the residue was recrystallized from methanol/ether to give XIE2008-...
Samples were injected in a 1 μl volume on the column and eluted as follows: for RPLC, the gradient went from 99% mobile phase A (0.1% formic acid in H2O) to 95% mobile phase B (0.1% formic acid in methanol) over 16 min. For HILIC, the gradient went from 99% mobile phase...
Why is an acid catalyst used in the reaction between benzoic acid and methanol? Why don't lipids and water mix? Explain why the SN1 mechanism is not used in the preparation of unsymmetrical ethers. Why is AlBr_3 an acidic salt?
What alcohol is formed when the given compound is treated with NaBH4 in CH3OH? Which of the following liquids has the lower boiling point: CH3CH2CH3 or CH3CH2OH? Explain. Which of the following alcohols is least soluble in water? methanol, CH_3OH n-butanol, C_4H_9OH n-pentanol...
solubility (thx for your patience btw), I have Benzoic acid, Nitroaniline and anthracene, so I need an extraction solvent that is not miscible in water so it can contain my organic layer that's the first condition, the second condition is that my 3 molecules need to be soluble in it ...
DMAP (m.p. 112-113°C) and PPY (m.p. 57-58°C) are colorless, crystalline substances which are very soluble in methanol, ethyl acetate, chloroform, methylene chloride, 1,2-dichloroethane, acetone, and acetic acid and less soluble in cold hexane, cyclohexane, and water. DMAP can be rec...

a ratio of 8:2. The bands were marked under the UV wavelengths 254 and 365 nm, and the target band was scrapped using a scalpel and crushed into a powder. It was added to absolute methanol and then filtered using a syringe filter (Agilent, USA) and kept in a glass vial at 4 °C...
