How do you make o-Dianisidine solution?

How do you make o-Dianisidine solution?

Preparation Instructions Prepare the o-Dianisidine Solution by reconstituting one vial of o-dianisidine dihydrochloride (Catalog Number F5803) with 20 ml water. Prepare the PGO Enzymes Solution by adding the contents of 1 capsule of PGO Enzymes (Catalog Number P7119) to 100 ml of water in an amber bottle.

What is O-Dianisidine dihydrochloride?

o-Dianisidine (3,3′-dimethoxybenzidine) is a peroxidase substrate suitable for use in ELISA procedures. This substrate produces a soluble end product that is yellow-orange in color and can be read spectrophotometrically at 405 nm.

Is Dianisidine dihydrochloride a dye?

Benzidine derivatives, such as 3,30-dimethylbenzidine and 3,30-dimethoxybenzidine (o-dianisidine) (Figure 25), are used as dyes or intermediates for dyestuffs or pigments (e.g., Trypan Blue, Acid Red 14, Direct Blue 1, 8, 15, 76, 98, 218, and Pigment Orange 16), coatings, plastics, or in chemical studies.

Which is the correct formula for o dianisidine?

Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). o-Dianisidine is an organic compound with the formula [ (CH 3 O) (H 2 N)C 6 H 3] 2. A colorless or white solid, it is a bifunctional compound derived via the benzidine rearrangement from o -anisidine .

Can a direct blue dye be o dianisidine?

Where the ROOR’ can be hydrogen peroxide, and the electron doner be o -dianisidine. Direct Blue 1 is commercial dye, a derivative of o-dianisidine. The manufacture and degradation of o -dianisidine, like other benzidene derivatives, has attracted regulatory attention.

Which is the precursor to azo dye o-dianisidine?

o -Dianisidine is a precursor to some azo dyes by formation of the bis( diazonium) derivative, which is coupled to diverse aromatic compounds. Some commercial dyes derived from o -dianisidine include C. I. Direct Blue 1, 15, 22, 84, and 98. o -Dianisidine is also used in assaying activity of peroxidase in lab.
