Is azobenzene toxic?
Ingestion: Causes gastrointestinal irritation with nausea, vomiting and diarrhea. May be harmful if swallowed. Azobenzene induced invasive sarcomas in the spleen and other abdominal organs in male and female rats following dietary administration. Inhalation: May cause respiratory tract irritation.

Is azobenzene a carcinogen?
Cancer Assessment Azobenzene induced invasive sarcomas in the spleen and other abdominal organs in male and female F344 rats following dietary administration. It is genotoxic and may be converted to benzidine, a known human carcinogen, under the acidic conditions in the stomach.
Is azobenzene an organic acid or amine?
Azobenzene is neither an amine nor an organic acid an amine an organic acid Question 12 2 pts In this lab, we will be using benzoic acid.
Why is azobenzene non fluorescent?
Azobenzenes efficiently undergo photoisomerization in the photoexcited state, and this process is surely a reason for their non-fluorescence. Photoisomerization accompanies the change in the direction of the lone pair of one nitrogen atom.
What are the effects of exposure to azobenzene?
It is probably combustible. SYMPTOMS: Symptoms of exposure to this compound may include irritation of the skin, eyes and respiratory tract; liver and kidney damage; liver and lung cancer; and possible blood disorders.
What kind of crystal is azobenzene made of?
Azobenzene appears as orange-red crystals or dark brown chunky solid. (NTP, 1992) Azobenzene is a molecule whose structure comprises two phenyl rings linked by a N=N double bond; the parent compound of the azobenzene class of compounds.
Which is the parent compound of the chemical azobenzene?
Azobenzene appears as orange-red crystals or dark brown chunky solid. (NTP, 1992) CAMEO Chemicals. Azobenzene is a molecule whose structure comprises two phenyl rings linked by a N=N double bond; the parent compound of the azobenzene class of compounds.
Why are azobenzenes used in hydrogels and monomers?
Azobenzenes have been reported as the most commonly employed materials (either as monomers or cross-linkers in hydrogels) to induce reversible photo-responsive phase transitions in response to polarized light (wavelength 360 and 440 nm) via polarity and hydrophobicity effects.
