Benzophenone imine plays a vital role as an ammonia surrogate. It is primarily used as ammonia equivalents for the selective formation of protected primary amines. Benzophenone imine is useful as a synthetic intermediate, especially for the synthesis of glycine Schiff base. Benzophenone imine is useful for the preparation of nitrile yield dimers.

Fluorinert™ belongs to the group of aliphatic compounds. It is considered as a pressure-transmitting medium because it is highly inert. Fluorinert™ Electronic Liquid FC-770 is a thermally stable, fully-fluorinated liquid that has ideal properties for use as a heat transfer fluid in a variety of industries. The inertness of Fluorinert™ FC-770 permits its use as a direct contact single and two-phase coolant in certain supercomputers and sensitive military electronics. Its high dielectric strength and electrical resistivity are ideal for applications in high voltage transformers and power electronics. In the semiconductor manufacturing industry, its wide liquid range makes Fluorinert™ liquid FC-770 suited for cooling ion implanters, dry etchers and CVD machines. Its low pour point also permits its use in thermal shock and test equipment.

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.

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.
