In the first step, an N-phenyl-1,2-diaminobenzene (N-phenyl-o-phenylenediamine) is converted into a diazonium salt which instantaneously forms a 1,2,3-triazole. The triazole is unstable and at elevated temperatures, nitrogen is released and the carbazole is formed. [11] [12] Fluorescence of (9H-carbazol-9-yl)(2,4-dichlorophenyl) methanone
An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.
3-Amino-9-ethylcarbazole (AEC) is a chemical compound commonly used as a chromogenic substrate in immunohistochemistry, specifically for visualizing sections stained with HRP-conjugated secondary antibodies. [1]
Pigment violet 23 is an organic compound that is a commercial pigment.It is member of the dioxazine family of heterocyclic compounds, but derived from carbazoles. [1] It is prepared by condensation of chloranil and 3-amino-N-ethylcarbazole.

Sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) is a method of separating molecules based on the difference of their molecular weight. At the pH at which gel electrophoresis is carried out the SDS molecules are negatively charged and bind to proteins in a set ratio, approximately one molecule of SDS for every 2 amino acids.
e-SDS, otherwise known as an extended SDS.An extended SDS is a document of chemical safety. It is much longer and detailed than the standard SDS. It consists of a standard SDS which has more subsections than the general one, and an additional annex containing one or more exposure scenario(s).
1-Ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC, EDAC or EDCI) is a water-soluble carbodiimide usually handled as the hydrochloride. [1]It is typically employed in the 4.0-6.0 pH range.
