3,3'-DIMETHOXYBENZIDINE Chemical Properties,Uses,Production

Chemical Properties

Grey fine crystals

Uses

  1. o-Dianisidine (3,3'-DIMETHOXYBENZIDINE) is a colorless or Light purple to brown, highly toxic, crystalline compound that turns violet when exposed to air.
  2. manufacture of azo dyes and pigments. o-Dianisidine is used as an intermediate for the preparation of azo dyes, pigments and o-dianisidine diisocyanate, which finds application in adhesives, polyurethane elastomers and resins.
  3. o-Dianisidine is used for the detection of Au, Co, Cu, SCN-, V; determination of Au, NO2-, Ce(IV) (spectrophotometrically).
  4. Ortho Dianisidine may be used in a novel automated method, used to measure the total antioxidant response (TAR) against potent free radical reactions. It may also be used along with glucose oxidase and peroxidase in the determination of blood and urinary glucose.
  5. o-Dianisidine is used as a redox indicator.
  6. It is also used in various industries like leather, paper, plastics, rubber, and textiles.
  7. It acts as a reagent to detect metals, thiocyanates, and nitrites.
  8. Exposure to this substance causes skin irritation and sensitization. Dianisidine is reasonably anticipated to be a human carcinogen based on evidence of carcinogenicity in experimental animals. (NCI05)

General Description

Colorless crystals or a light brown powder. Turns violet on standing. Carcinogen.

Air & Water Reactions

Finely powdered material is a significant dust explosion hazard. Insoluble in water.

Reactivity Profile

3,3'-DIMETHOXYBENZIDINE is a weak base. Reacts exothermically with acids. Sensitive to heat, air and prolonged exposure to light.

Fire Hazard

3,3'-DIMETHOXYBENZIDINE is combustible.

Safety Profile

Confirmed carcinogen with experimental tumorigenic data. Moderately toxic by ingestion. Mutation data reported. Combustible when exposed to heat or flame. When heated to decomposition it emits toxic fumes of NOx.
