2-Amino-4-fluorobenzamide (cas: 119023-25-5) belongs to amides. The solubilities of amides and esters are roughly comparable. Typically amides are less soluble than comparable amines and carboxylic acids since these compounds can both donate and accept hydrogen bonds. Tertiary amides, with the important exception of N,N-dimethylformamide, exhibit low solubility in water. The presence of the amide group –C(=O)N– is generally easily established, at least in small molecules. It can be distinguished from nitro and cyano groups in IR spectra. Amides exhibit a moderately intense νCO band near 1650 cm−1. By 1H NMR spectroscopy, CONHR signals occur at low fields. In X-ray crystallography, the C(=O)N center together with the three immediately adjacent atoms characteristically define a plane.Reference of 119023-25-5

Synthesis of 1,2,3-benzotriazin-4-one derivatives containing spirocyclic indoline-2-one moieties and their nematicidal evaluation was written by Wang, Gao-Lei;Chen, Xi;Chang, Ya-Ning;Du, Dan;Li, Zhong;Xu, Xiao-Yong. And the article was included in Chinese Chemical Letters in 2015.Reference of 119023-25-5 This article mentions the following:

To discover new chemotypes of nematicides with proper toxicol. profiles, a series of novel 1,2,3-benzotriazin-4-one derivatives were synthesized and further bioevaluated. The bioassay results showed that most of the synthesized compounds were endowed with moderate to good control efficacy against Meloidogyne incognita at 10.0 mg/L in vivo. Among them, compounds 1-(4-(4-oxo-7-methoxylbenzo[d][1,2,3]triazin-3(4H)-yl)butyl)spiro[indoline-3,2′-[1,3]dioxolan]-2-one and 1-(4-(4-oxo-7-nitrobenzo[d][1,2,3]triazin-3(4H)-yl)butyl)spiro[indoline-3,2′-[1,3]dioxolan]-2-one displayed 100% inhibitory activities at this concentration, which implied that they could be used as lead compounds for promising nematicides. In the experiment, the researchers used many compounds, for example, 2-Amino-4-fluorobenzamide (cas: 119023-25-5Reference of 119023-25-5).
