Benzyldimethyltetramethylammonium chloride is a quaternary ammonium salt used in eye care and the treatment of eye diseases. It serves as an ion association reagent for extraction photometric analysis and acts as a sensitizer in metal photometric determinations. It is soluble in water and ethanol in any proportion and can be used in combination with cationic, nonionic surfactants, or dyes. However, it should not be used with anionic surfactants or additives. It is stable in weak acids and alkalis but should not be heated for extended periods above 100°C.

Product Application of Tetradecyldimethylbenzylammonium chloride (CAS#139-08-2)
Serves as an ion-association reagent in extraction photometric analysis and acts as a sensitizer in metal photometric determination. It is freely soluble in both water and ethanol in any ratio, and compatible with cationic or nonionic surfactants as well as dyes. Use with anionic surfactants or additives should be avoided. The compound remains stable in weak acidic and alkaline conditions but should not be exposed to prolonged heating above 100 °C.
