Bitolylene Diisocyanate (TODI) from Canada

Bitolylene diisocyanate (TODI), also known as 3,3'-bitolylene-4,4'-diisocyanate, is an aromatic diisocyanate explicitly named in HTS 2929.10.20.00 due to its two isocyanate groups on a bitolyl structure. It serves as a key raw material in high-performance polyurethane elastomers and coatings, valued for thermal stability. As a separate chemically defined organic compound with nitrogen functions, it fits Chapter 29's scope for isocyanates.
