General description

2-Amino-5-chlorophenol can be synthesized from 2-chloro-5-nitrophenol via reduction. It can also be obtained from 1-chloro-4-nitrobenzene by using a bacterial strain LW1. 2-Amino-5-chlorophenol participates in the condensation reaction with acetylferrocene to afford ferrocenyl Schiff bases bearing a phenol group.

Application

2-Amino-5-chlorophenol may be used to synthesize 2-amino-5-chloromuconic semialdehyde and benzoxazole derivatives.

Comamonas strain CNB-1 was isolated from a biological reactor treating wastewater from a p-chloronitrobenzene production factory. Strain CNB-1 used p-chloronitrobenzene as sole source of carbon, nitrogen, and energy. A 2-aminophenol 1,6-dioxygenase was purified from cells of strain CNB-1. The purified

Bacterial strain LW1, which belongs to the family Comamonadaceae, utilizes 1-chloro-4-nitrobenzene (1C4NB) as a sole source of carbon, nitrogen, and energy. Suspensions of 1C4NB-grown cells removed 1C4NB from culture fluids, and there was a concomitant release of ammonia and chloride.

Comamonas sp. strain CNB-1 grows on 4-chloronitrobenzene (4-CNB) and nitrobenzene as sole carbon and nitrogen sources. In this study, two genetic segments, cnbB-orf2-cnbA and cnbR-orf1-cnbCaCbDEFGHI, located on a newly isolated plasmid, pCNB1 (ca. 89 kb), and involved in 4-CNB/nitrobenzene degradation
