At room temperature, it is a white crystalline powder with a fine crystal structure. It is hygroscopic and readily deliquesces into a paste when exposed to air. Due to the extremely strong hygroscopicity of pure products, they are mostly supplied in the form of aqueous solutions or alcohol solutions (such as methanol and ethanol solutions) in industry, with concentrations typically ranging from 10% to 50%.

SAFETY INFORMATION

PRODUCT USAGE

Tetrabutylammonium Hydroxide is a strong alkaline quaternary ammonium salt, appearing as a colorless and transparent liquid. It is easily soluble in water and ethanol, with strong alkalinity, good solubility and phase transfer catalytic performance, and no obvious irritation. Its core application is in the field of organic synthesis, serving as a phase transfer catalyst to accelerate the reaction between aqueous and organic phases, improving reaction efficiency and product purity. It can also be used as an alkaline catalyst for drug synthesis and spice preparation. In addition, it is used in the synthesis of organosilicon materials, acid-base titration analysis, and cleaning in the semiconductor industry, being an essential key raw material in fine chemical, pharmaceutical and electronic fields.
