Product Introduction

Youdaoplaceholder0 Bromide is composed of four propyl (-C₃H₇) groups linked to a nitrogen atom to form a quaternary ammonium cation ([(C₃H₇)₄N]⁺), which combines with a bromide ion (Br⁻) to form an ionic compound. It is soluble in water and polar organic solvents such as methanol, ethanol, and acetone. White crystalline powder or crystal, colorless and transparent when the purity is relatively high.
