White to Off-White Low-Melting Solid

??

Benzyldodecyldimethylammonium bromide has been used in a study to assess the relation between chemical structure and germicidal efficacy in surface-active cations. It has also been used in a study to investigate pore size control during the synthesis of macroporous thermosensitive poly(N-isopropylacrylamide) hydrogels.

?? ??

Benzyldodecyldimethylammonium bromide is a cationic surfactant that may be used as an adsorbent for certain metals such as Cr(VI).

Safety Profile

Poison by ingestion andintraperitoneal routes. Whenheated to decomposition it emits very toxic fumes ofNH3, NOx, and Br -
