Mequinol is a common active ingredient in topical drugs used for skin depigmentation.As a topical drug mequinol is often mixed with tretinoin, a topical retinoid.A common formulation for this drug is an ethanolic solution of 2% mequinol and 0.01% tretinoin by mass. [1]
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
Methoxyacetic acid is a colorless, viscous, and corrosive liquid with a pungent odor which, at 7 °C, freezes to a mass similar to glacial acetic acid. Due to the low solvation energy of its methoxy group, methoxyacetic acid, with a pKa value of 3.57, is more acidic than acetic acid (pKa 4.757) and glycolic acid (pKa 3.832). [3]
The conversion of methyl acetate back into its components, by an acid, is a first-order reaction with respect to the ester. The reaction of methyl acetate and a base, for example sodium hydroxide, is a second-order reaction with respect to both reactants. Methyl acetate is a Lewis base that forms 1:1 adducts with a variety of Lewis acids.
Olefin metathesis has been widely studied. One of the synthesis pathways for octyl methoxycinnamate includes cross metathesis. The high efficiency of the nitro-Grela catalyst has been used in the cross metathesis of trans-anethole with 2-ethylhexyl acrylate to produce octyl methoxycinnamate (86% yield).
Anisyl acetate (4-methoxybenzyl acetate) is an acetate ester of anisyl alcohol. It is a naturally occurring flavor found in various fruits and types of vanilla . [ 1 ] It is also used as a flavoring agent to produce a flavor profile described variously as sweet, smooth, fruity (cherry or plum) and vanilla or almond.
This residue contains a few percent by weight of phenol and cresols. Industrially, p-cresol is currently prepared mainly by a two-step route beginning with the sulfonation of toluene: [4] CH 3 C 6 H 5 + H 2 SO 4 → CH 3 C 6 H 4 SO 3 H + H 2 O. Basic hydrolysis of the sulfonate salt gives the sodium salt of the cresol: CH 3 C 6 H 4 SO 3 H + 2 ...
para-Methoxyfentanyl or p-methoxyfentanyl or 4-methoxyfentanyl is a potent short-acting synthetic opioid analgesic drug. It is an analog of fentanyl , with similar effects but slightly lower potency.
