Descrizione: Phloroglucinol (phlo) is a phenol derivative that shows a cytoprotective effect from oxidative damage by enhancing the activity of cellular catalase. It can also be used to prepare synthetic analogs of A-type proanthocyanidins (PACs) such as 2,8-dioxabicyclo nonane derivatives by reacting with the corresponding flavylium salts. Phlo can react with benzaldehyde derivatives to form phloroglucinol-based microporous polymeric organic frameworks (phlo-POF) with potential applications in ion exchange and gas adsorption. Phloroglucinol is an antispasmodic and a derivative of phenol.

Descrizione: Tetramethylrhodamine isothiocyanate Isomer R (TRITC) is the R isomer of tetramethylrhodamine isothiocyanate and is also known as 6-tetramethylrhodamine isothiocyanate. It is a strongly fluorescent compound soluble in ethanol, methanol, dimethylformamide, dimethylsulfoxide, and water. TRITC is a moderately-sized aminoxanthene dye carrying carboxylic acid and isothiocyanate substituents on the non-planar pendant phenyl ring. It forms a lipophilic cation in acidic pH and a hydrophilic zwitterion around neutral pH. The isothiocyanate group reacts with nucleophilic substituents (e.g., amino, hydroxyl, thiol) of biomolecules, providing the means of attaching a fluorescent label. TRITC also reacts with water and hydroxide ions and is unstable in aqueous solutions. TRITC is commercially available as a zwitterion or as a chloride.

Descrizione: o-Tolidine is a diacidic dye which is sparingly soluble in water and easily soluble in ether and alcohol. On exposure to chlorine or bromine vapors, it forms an intense blue color. This forms the basis for detection of chlorine, nitrates and hydrogen peroxide in air or water. It turns yellow on reacting with free chlorine. o-Tolidine easily forms acid salts.
