N-Phenylglycine is an organic compound with the formula C6H5NHCH2CO2H. This white solid achieved fame as the industrial precursor to indigo dye.[1] It is a non-proteinogenic alpha amino acid related to sarcosine, but with an N-phenyl group in place of N-methyl.

Preparation

[edit]

It is prepared by the Strecker reaction involving the reaction of formaldehyde, hydrogen cyanide, and aniline. The resulting amino nitrile is hydrolyzed to give the carboxylic acid.[2]

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
