Product Profile of Benzyldimethyltetramethylammonium Chloride
This quaternary ammonium salt is primarily employed in ophthalmic care and ocular disease treatment formulations. It functions as an ion-association reagent for extraction photometric analysis and enhances sensitivity in metal detection through photometric methods. The compound exhibits complete miscibility with both water and ethanol in any proportion, and demonstrates compatibility with cationic/nonionic surfactants and colorants. It is chemically stable in weakly acidic and alkaline environments, though prolonged heating above 100°C should be avoided. Notably, formulations should exclude anionic surfactants or additives to maintain system stability.

Product Application of Tetradecyldimethylbenzylammonium Chloride (CAS# 139-08-2)
This quaternary ammonium compound functions as a highly effective ion-association reagent in extraction photometric analysis and enhances detection sensitivity in metal determination methods. It demonstrates complete miscibility with water and ethanol in all proportions, and exhibits excellent compatibility with cationic and nonionic surfactants as well as dye components. While stable under weakly acidic and alkaline conditions, the compound requires protection from prolonged thermal exposure above 100°C. Anionic surfactants and additives should be specifically excluded from formulations containing this substance.
