product description
Dodecyltrimethylammonium bromide is a white to off-white crystalline powder or crystal. The pure substance is a colorless crystal and is prone to absorbing moisture when exposed to air. It is highly soluble in water, forming a transparent solution. The aqueous solution is weakly alkaline (pH approximately 8 to 9, due to the hydrolysis of quaternary ammonium salts).
