1-(4-Nitrophenyl)glycerol is a useful additive for controlling swarming of Proteus bacteria on culture media.

2-Naphthyl caprylate is a chromogenic substrate for carboxylesterase and lipase. 2-naphthol is released upon hydrolyzation. By simultaneous coupling with a diazonium salt, the corresponding azo-dye is formed.

Naphthols can also be detected by fluorescence analysis, and can be used in a colorimetric assay for the extracellular lipase of Pseudomonas fluorescent B52.

2-Naphthyl myristate is a substrate for carboxylesterase. When coupled with a diazonium salt an azo-dye is formed. It can also be detected via fluorescence analysis.

2-Naphthyl-beta-D-galactopyranoside is a substrate for beta-galactosidase. 2-naphthol is released upon hydrolyzation. By simultaneous coupling with a suitable staining reagent, such as hexazonium p-rosaniline, the corresponding red-brown azo-dye is formed. Naphthols can also be detected by fluorescence analysis.

2-Naphthyl-α- L-fucopyranoside is a chromogenic substrate for α-L-Fucosidase. 2-naphthol is released upon hydrolyzation. By simultaneous coupling with a suitable staining reagent, such as hexazonium p-rosaniline, the corresponding azo-dye is formed. Naphthols can also be detected by fluorescence analysis.

2-Naphthyl-α-D-glucopyranoside is a substrate for α-glucosidase. 2-naphthol is released upon hydrolyzation. By simultaneous coupling with a suitable staining reagent, such as hexazonium p-rosaniline, the corresponding red-brown azo-dye is formed. Naphthols can also be detected by fluorescence analysis.

2-Nitrophenyl-1-thio-β-D-galactopyranoside is an enzyme substrate that is often used in the detection of lac- mutations.

2-Nitrophenyl-N-acetyl- β-D- glucosaminide is a chromogenic β-glucosaminidase substrate yielding a yellow solution upon cleavage.

2-Nitrophenyl-β-D-galactopyranoside or ONPG is a chromogenic substrate for β-galactosidase. Upon hydrolysis, ONPG releases galactose along with a chromogenic yellow compound. Additionally, ONPG is a substrate useful for the determination of β-glucosidases.

4-Nitroindole is used in the synthesis of a variety of compounds including: indoles, nucleosides, CB2 cannabinoid receptor ligands, CGRP receptor antagonists, anti-angiogenic agents, meridianin derivatives, tryptophan dioxygenase inhibitors, and 1,3,4,5-tetrahydropyrrolo-[4,3,2-de]quinoline.

4-Nitrophenyl phosphate, disodium salt hexahydrate is a chromogenic substrate yielding a soluble yellow chromophor for the colorimetric assay of phosphatases and is used for determining alkaline phosphatase activity in human serum.

4-Nitrophenyl beta-D-cellobioside is a chromogenic substrate for beta-D-Cellobiosidase and yields a yellow solution upon cleavage.

4-Nitrophenyl-beta-L-fucopyranoside is a chromogenic substrate for beta-D-Fucosidase that yields a yellow solution when cleaved.
