General Description
Gray-black crystalline solid or light gray powder. May be carcinogenic.
Reactivity Profile
O-ANISIDINE HYDROCHLORIDE(134-29-2) reacts as an acid to neutralize bases. These neutralizations generate some heat, Usually does not react as either oxidizing agents or reducing agents but such behavior is not impossible. May catalyze organic reactions.
Air & Water Reactions
Water soluble.
Potential Exposure
Anisidines are used in the manufacture
of azo dyes; pharmaceuticals; textile-processing chemicals
Incompatibilities: Incompatible with oxidizers (chlorates,
nitrates, peroxides, permanganates, perchlorates, chlorine,bromine, fluorine, etc.); contact may cause fires or explosions.
Keep away from alkaline materials, strong bases,
strong acids, oxoacids, epoxides. Attacks some coatings
and some forms of plastic and rubber.
Fire Hazard
Flash point data for this chemical are not available; however, O-ANISIDINE HYDROCHLORIDE is probably combustible.
First aid
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately.
If this chemical has been inhaled, remove from exposure,
begin rescue breathing (using universal precautions, including
resuscitation mask) if breathing has stopped and CPR
if heart action has stopped. Transfer promptly to a medical
facility. When this chemical has been swallowed, get medical
attention. Give large quantities of water and induce
vomiting. Do not make an unconscious person vomit.
Shipping
UN2431 Anisidines, Hazard Class: 6.1; Labels:
6.1-Poisonous materials
Chemical Properties
Anisidine exists as ortho-, meta-, and paraisomers.
They have characteristic amine (fishy) odors.
Waste Disposal
Dissolve in combustible solvent
(alcohols, benzene, etc.) and spray solution into furnace
equipped with afterburner and scrubber, or burn spill
residue on sand and soda ash absorbent in a furnace.
Uses
o-Anisidine hydrochloride is used as a chemical intermediate in the production of numerous azo and triphenylmethane dyes and pigments (e.g., C.I. direct red 72, disperse orange 29, direct yellow 44, direct red 24, and acid red 4); in the production of pharmaceuticals, including the expectorant guaiacol; as a corrosion inhibitor for steel; and as an antioxidant for polymercaptan resins (IARC 1999, HSDB 2009).
Carcinogenicity
o-Anisidine is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity in experimental animals.
