4-Bromobenzaldehyde, or p-bromobenzaldehyde, is an organobromine compound with the formula BrC 6 H 4 CHO. It is one of three isomers of bromobenzaldehyde . [ 3 ] It displays reactivity characteristic of benzaldehyde and an aryl bromide .
Methyl benzoate is an organic compound. It is an ester with the chemical formula C 6 H 5 COOCH 3 , sometimes abbreviated as PhCO 2 Me , where Ph and Me are phenyl and methyl , respectively. Its structure is C 6 H 5 −C(=O)−O−CH 3 .
Methyl 4-bromophenylacetate is made from 4-bromophenylacetic acid by Fischer esterification, refluxing it with methanol acidified with sulfuric acid. [3] An ethyl ester can be made in an analogous way using ethanol instead of methanol. [4] A hydrazone derivative, 2-(4-bromophenyl)acetohydrazide, is made by refluxing the methyl ester with ...
Propyl benzoate has a nutty odor and sweet fruity or nut-like taste, and as such, it is used as a synthetic flavoring agent in foods. It also has antimicrobial properties and is used as a preservative in cosmetics.
A supersaturated solution of sodium acetate in water is supplied with a device to initiate crystallization, a process that releases substantial heat. Solubility from CRC Handbook. Sodium acetate trihydrate crystals melt at 58–58.4 °C (136.4–137.1 °F), [12] [13] and the liquid sodium acetate dissolves in the released water of crystallization.
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.
Benzyl bromide is used in organic synthesis for the introduction of the benzyl groups when the less expensive benzyl chloride is insufficiently reactive. [6] [7] Benzylations are often achieved in the presence of catalytic amounts of sodium iodide, which generates the more reactive benzyl iodide in situ. [3]
3,4,5-Trimethoxybenzaldehyde can be used as an intermediate in the synthesis of some pharmaceutical drugs including trimethoprim, [1] [2] cintriamide, roletamide, trimethoquinol (aka tretoquinol), and trimazosin as well as some psychedelic phenethylamines.
