Methyl benzoate can be isolated from the freshwater fern Salvinia molesta. [3] It is one of many compounds that is attractive to males of various species of orchid bees, which apparently gather the chemical to synthesize pheromones; it is commonly used as bait to attract and collect these bees for study.
They are of two types: Formed by replacing the hydrogen atom in the –COOH by some other radical, usually an alkyl or aryl radical forming an ester. For example, methyl benzoate is a molecular compound with the structure C 6 H 5 –CO–O–CH 3, and its condensed structural formula usually written as C 6 H 5 COOCH 3.

Benzoate plasticizers, such as the glycol-, diethyleneglycol-, and triethyleneglycol esters, are obtained by transesterification of methyl benzoate with the corresponding diol. [22] These plasticizers, which are used similarly to those derived from terephthalic acid ester, represent alternatives to phthalates .
General chemical structure of a paraben (a para-hydroxybenzoate) where R = an alkyl group. Parabens are chemicals that are commonly used as preservatives in cosmetic and pharmaceutical products. Chemically, they are a series of parahydroxybenzoates or esters of parahydroxybenzoic acid (also known as 4-hydroxybenzoic acid). Research is being ...
The two most popular NAD precursors, NR or NMN, are more stable and available, especially as oral supplements, says Martens. "NAD itself is not as stable, so it's not quite as efficient to take a ...
Benzyl group and derivatives: Benzyl group, benzyl radical, benzyl amine, benzyl bromide, benzyl chloroformate, and benzyl methyl ether. R = heteroatom, alkyl, aryl, allyl etc. or other substituents. In organic chemistry, benzyl is the substituent or molecular fragment possessing the structure R−CH 2 −C 6 H 5.
The bowl announced before the season that a matchup of Big 12 teams was possible with the two pools of teams it had to pick from. The “Big 12 pool” contained the 12 teams that were in the ...
