Usage
Electronic-grade semiconductor cleaning and developing agents: Used as developing agents for high-purity positive photoresists and as alkaline chemical cleaning agents for silicon wafer surfaces during semiconductor, wafer manufacturing, and flat panel display processing, ensuring no metal ion residue.
High-efficiency phase transfer catalysts (PTCs): Serving as crucial phase transfer catalysts in organic synthesis and fine chemicals. They guide cross-interfacial reactions between heterogeneous systems.
Molecular sieve and nanomaterial directing agents: Serving as indispensable structure directing agents (templating agents) in the synthesis of zeolite molecular sieves.
Analytical chemistry titrants: Used as standard strong-base titrants for determining weak acids in non-aqueous titration analysis.
