The benzamide derivatives with morpholine or benzene rings reveal no antifungi activity.
In recent years, numerous studies have reported various analytical methods for qualitative and quantitative estimation of morpholine. These analytical methods employed various available analytical techniques, such as gas chromatography (GC) [15-17], gas chromatography-mass spectrometry (GC-MS) [18], gas-liquid chromatography-high resolution mass spectrometry (GLC-MS) [19], liquid chromatography (LC) [20], ultra performance liquid chromatography (UPLC) [21], hydrophilic interaction liquid chromatography with electrospray ionization and tandem mass spectrometry (HILIC-ESI-MS/MS) [22], and ultrahigh performance liquid chromatography-high resolution mass spectrometry (UHPLC-HRMS) [14].

He also added, "We are a reputed manufacturer & exporter of drug intermediates such as Bis(2-chloroethyl)amine hydrochloride 821-48-7, 2-Chloroethyl Amine Hydrochloride, 2-chloroethyl morpholine hcl, 4-(2-Chloroethyl)morpholine hydrochloride 3647-69-6, Chloroethyl Morpholine Hcl & many more.
A special attention was paid to the N-substituted amides (co)polymers such N-isopropyl acrylamide (NIPAM), N-methyl methacrylamide (NMMAM), N-acryloyl morpholine (NaM), and so forth [9,10].

Therefore, many organic and inorganic solvent systems such as N-methyl morpholine N-oxide (NMMO) [3] lithium chloride/1,3dimethyl-2-imidazolidinone (LiCl/DMI) [28] lithium chloride/N,N dimethylacetamide (LiCl/DMAc) [29] and phosphoric acid [17] have been investigated for regenerated cellulose fiber production.
In this case, the NMR analysis identified the formation of morpholine end groups arising from the attack of neighboring hydroxyl groups, which possibly correspond to the main chain transfer reaction.
