4-Nitrothiophenol
chemical compound
4-Nitrothiophenol is an organosulfur compound with the formula HSC6H4NO2. It exists as a yellow solid that is soluble in several organic solvents. It is one of three isomers of nitrothiophenol. It was originally prepared by sulfidation of 4-nitrochlorobenzene, which was improved by intentionally generating a polysulfide intermediate. 4-Nitrothiophenol is closely related to thiophenol but more acidic.
The compound reacts with chlorine to give 4-nitrophenylsulfenyl chloride, a useful reagent. It has also been used as a probe of plasmon-induced reactions.
The public source identifies “4-Nitrothiophenol” as chemical compound. This brief keeps that definition visible, then builds a research path around 4-Nitrothiophenol, chemical and compound.
Why this record matters
A short description can identify a subject without explaining its stakes. For “4-Nitrothiophenol”, the useful work is to connect “chemical compound” to the records capable of establishing context and consequence.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Dec 15, 2025. The linked authority identifier is Q72496343. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
