o-Anisidine

A colorless liquid, commercial samples can appear yellow owing to air oxidation.

It is prepared via methanolysis of 2-chloronitrobenzene:[5] The resulting o-nitroanisole is reduced to o-anisidine.

This mixture is applied to the wood and by reaction with polyphenols in the heartwood a reddish brown azo dye is formed.

o-Anisidine is a dangerous pollutant from the production of dyes.

[6] The International Agency for Research on Cancer (IARC) has classified o-anisidine as a Group 2B, possible human carcinogen.

NFPA 704 four-colored diamond Health 2: Intense or continued but not chronic exposure could cause temporary incapacitation or possible residual injury. E.g. chloroform Flammability 1: Must be pre-heated before ignition can occur. Flash point over 93 °C (200 °F). E.g. canola oil Instability 0: Normally stable, even under fire exposure conditions, and is not reactive with water. E.g. liquid nitrogen Special hazards (white): no code
