4-Nitrocatechol
4-Nitrocatechol is the by-product of the hydroxylation of 4-Nitrophenol by the human cytochrome P450 (CYP) 2E1. This reaction is a useful metabolic marker for the presence of functional cytochrome P450 2E1 in mammalian cell microsomes. Hepatic and extrahepatic microsomal cytochrome P450 isozymes further catalyze the reduction of p-nitrocatechol to p-aminophenol.

4-Nitrophenol
4-Nitrophenol (also called p-nitrophenol or 4-hydroxynitrobenzene) is a phenolic compound that has a nitro group at the opposite position of the hydroxyl group on the benzene ring. It belongs to the class of organic compounds known as nitrophenols. Nitrophenols are compounds containing a nitrophenol moiety, which consists of a benzene ring bearing both a hydroxyl group and a nitro group on two different ring carbon atoms. 4-Nitrophenol shows two polymorphs in the crystalline state. The alpha-form is colorless pillars, unstable at room temperature, and stable toward sunlight. The beta-form is yellow pillars, stable at room temperature, and gradually turns red upon irradiation of sunlight. Usually 4-nitrophenol exists as a mixture of these two forms. 4-Nitrophenol can be used as a pH indicator and as an intermediate in the synthesis of paracetamol. Itis also used as the precursor for the preparation of phenetidine and acetophenetidine, indicators, and raw materials for fungicides. Bioaccumulation of this compound rarely occurs. In peptide synthesis, carboxylate ester derivatives of 4-nitrophenol may serve as activated components for construction of amide moieties. 4-Nitrophenol is a potentially toxic compound: it can cause eyes, skin, and respiratory tract irritations. It may also cause inflammation of those parts. It has a delayed interaction with blood and forms methaemoglobin which is responsible for methemoglobinemia -which is characterized by tissue hypoxia, as methemoglobin cannot bind oxygen-, potentially causing cyanosis, confusion, and unconsciousness. When ingested, it causes abdominal pain and vomiting. Prolonged contact with skin may cause allergic response. Genotoxicity and carcinogenicity of 4-nitrophenol are not known. The LD50 in mice is 282 mg/kg and in rats is 202 mg/kg. Outside of the human body, 4-Nitrophenol has been detected, but not quantified in cow milk. Conjugates are more polar than the parent compounds and therefore are easier to excrete in the urine.

4-hydroxy-3-nitrophenylacetate
4-hydroxy-3-nitrophenylacetate, also known as 3-nitro-4-hydroxyphenylacetic acid, is slightly soluble (in water). It is a mildly acidic compound. This metabolite is a member of the class of compounds known as nitrophenols. Nitrophenols are compounds containing a nitrophenol moiety, which consists of a benzene ring bearing both a hydroxyl group and a nitro group on two different ring carbon atoms. Free nitrotyrosine undergoes metabolism to form 3-nitro-4-hydroxyphenylacetic acid (NHPA) which is excreted in the urine (Wikipedia). However, it is not known whether NHPA is derived exclusively from metabolism of nitrotyrosine, or whether it can be formed by nitration of circulating para -hydroxyphenylacetic acid (PHPA), a metabolite of tyrosine (PMID: 12797864). Since the plasma concentration of PHPA is markedly higher than free nitrotyrosine (approx. 400-fold), the nitration of high-circulating endogenous PHPA to form NHPA becomes very significant and accounts for the majority of NHPA excreted in urine (PMID: 12797864).

Picric acid
Picric acid, also known as acide picrique or c.i. 10305, belongs to the class of organic compounds known as nitrophenols. Nitrophenols are compounds containing a nitrophenol moiety, which consists of a benzene ring bearing both a hydroxyl group and a nitro group on two different ring carbon atoms. Based on a literature review a significant number of articles have been published on Picric acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). Picric acid is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Picric acid is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources. Picric acid. CAS Common Chemistry.
