4-(4-Nitrophenyl)azoresorcinol Chemical Properties,Usage,Production
Description
Oxygen violet can be prepared by one-step reaction of p-nitroaniline and 1,3-benzenediol. Azo violet can be used to prepare an azobenzene photochromic liquid crystal compound. Photochromic liquid crystal compounds have both photochromic properties and liquid crystallinity, which has become a research hotspot in the field of information storage. Azobenzene-based liquid crystals are the most interesting photochromic liquid crystal materials in recent years due to their unique photoinduced cis-trans isomerism. Azobenzene compounds undergo reversible cis-trans isomerization under the action of light, which makes them have great potential applications in many aspects such as optical storage, photo-holography and optical information processing.
Chemical Properties
dark red to brown crystalline powder
Uses
4-(4-Nitrophenyl)azoresorcinol is used for the detection of magnesium with which it yields a bright blue color in alkaline solution and it also used to determine molybdenum with which it forms a red-violet complex: Nikitina, Andrianova, C.A. 75, 136789v (1971).
Uses
It is a derivitized resorcinol dye compound with an absorption maximum of 432 nm. Used as a pH indicator.
Definition
ChEBI: An azobenzene in which the phenyl rings are 4-nitro- and 2,4-dihydroxy-substituted respectively.
Biochem/physiol Actions
4-(4-Nitrophenylazo)resorcinol is a pH indicator.
Purification Methods
Crystallise the dye from EtOH. [Beilstein 16 H 181, 16 IV 1266.]
