Original sentence: 2-Nitrobenzaldehyde is a potential starting material for other chemicals as well, given the two relatively reactive groups attached to an aryl system.2-Nitrobenzaldehyde is an intermediate chemical for the synthesis of Indigo, a water-insoluble dye commonly used to dye jeans and other fabrics.Another potential method of production is the oxidative cleavage of 2-nitrostyrene.Cinnamaldehyde is nitrated in a solution of acetic anhydride in acetic acid, in high-yield to 2-nitrocinnamaldehyde.The synthesis of 2-nitrobenzaldehyde via nitration of benzaldehyde is problematic because this produces mostly 3-nitrobenzaldehyde, with yields being about 19% for the ortho-, 72% for the meta- and 9% for the para isomer.This is then oxidized to 2-nitrocinnamic acid and decarboxylated to the 2-nitrostyrene
Edited sentence: 2-Nitrobenzaldehyde is a potential starting material for other compounds, given the two relatively reactive groups attached to an aryl system.2-Nitrobenzaldehyde was an intermediate in an early route to Indigo, a water-insoluble dye commonly used to dye jeans and other fabrics.Cinnamaldehyde can also be nitrated in a solution of acetic anhydride in acetic acid, in high-yield to 2-nitrocinnamaldehyde.The main routes to nitrobenzaldehyde begin with the nitration of styrene and cinnamic acid followed by the conversions of the resulting  2-nitrostyrene and [[2-nitrocinnamic acid].The method was abandoned in the early part of the 20th century, being replaced by routes from phenylglycine and from aniline.The nitration of benzaldehyde is problematic produces mostly 3-nitrobenzaldehyde, with yields being about 19% for the ortho-, 72% for the meta- and 9% for the para isomer.This compound is then oxidized to 2-nitrocinnamic acid and decarboxylated to the 2-nitrostyrene
