Tetramethylbenzidine Usage And Synthesis
Chemical Properties

Tetramethylbenzidine is sensitive to prolonged exposure to light. Neutralizes acids in exothermic reactions to form salts plus water.Tetramethylbenzidine may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.

Description

Tetramethylbenzidine(TMB) is a chromogenic substrate used in staining procedures in immunohistochemistry as well as being a visualising reagent used in enzyme-linked immunosorbent assays (ELISA). It is a white solid that forms a pale blue-green liquid in solution with ethyl acetate. Tetramethylbenzidine is degraded by sunlight and by fluorescent lights. It is a soluble chromogen substrate for horseradish peroxidase detection systems. Tetramethylbenzidine is recommended for ELISA procedures.

Carcinogenicity

It is not known if Tetramethylbenzidine is carcinogenic and the evidence is contradictory: Tetramethylbenzidine is not mutagenic by the Ames test, and did not induce formation of tumors in a single-arm study of 24 rats. On that evidence, it has been used as a replacement for carcinogenic compounds such as benzidine and o-phenylenediamine.

Chemical PropertiesWhite or light yellow solid
Uses3,3,5,5-Tetramethyl benzidine is used as a reagent in a sensitive staining procedure for the detection of low levels of heme-associated peroxidase activity of cytochrome P-450 on SDS-polyacrylamide or agarose gel; non-carcinogenic substitute for benzidine as reagent for the detection of blood and determination of hemoglobin content.
General DescriptionPale yellow crystals or off-white powder.
Air & Water ReactionsInsoluble in water.
Reactivity ProfileTetramethylbenzidine is sensitive to prolonged exposure to light . Neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.
Fire HazardFlash point data for Tetramethylbenzidine are not available, however, Tetramethylbenzidine is probably combustible.
