N-tert-Butyl-2-benzothiazolesulfenamide, commonly known as TBBS (or BBTS, Delac NS, Santocure NS, Vulkacit NZ), is a pivotal organic chemical compound playing a critical role in the modern rubber industry. With a CAS number of 95-31-8 and a molecular formula of C11H14N2S2, this compound boasts a molecular weight of 238.37 g/mol. It typically appears as a white to off-white solid or powder, characterized by a melting point ranging from 105°C to 110°C and a density of approximately 1.29 g/cm3 at 25°C.

The primary application of N-tert-Butyl-2-benzothiazolesulfenamide is its function as a high-performance sulfenamide vulcanization accelerator. This makes it indispensable for the processing of various rubber types, including natural rubber (NR), styrene-butadiene rubber (SBR), cis-1,4-polybutadiene rubber (BR), and polyisoprene rubber (IR). Its distinct advantages lie in its exceptional anti-incipient scorch properties, which provide a safer processing window, combined with a remarkably fast vulcanization rate. This dual benefit ensures efficient and high-quality rubber product manufacturing, reducing production time and improving overall material integrity.

TBBS is particularly beneficial in formulations involving higher alkalinity furnace-treated carbon black. Beyond its technical merits, N-tert-Butyl-2-benzothiazolesulfenamide gained significant prominence as a safer and environmentally more responsible alternative to certain traditional accelerators, most notably N-morpholinyl benzothiaolesulfenamide (NOBS). Recognizing the potential carcinogenicity associated with secondary amines found in NOBS, regulatory bodies, such as Germany in 1994, stipulated its replacement with alternatives like CBS (CZ) or TBBS in the tire industry. This shift underscores TBBS's commitment to both performance and safety standards.

From a safety perspective, N-tert-Butyl-2-benzothiazolesulfenamide is classified with hazard statements indicating it may cause an allergic skin reaction (H317) and is very toxic to aquatic life with long-lasting effects (H410). Proper handling, including wearing protective gloves and avoiding release to the environment, is crucial. It is non-flammable and should be stored in a dark, dry, and cool place, sealed properly and away from incompatible materials. Its synthesis typically involves the reaction of 2-Mercaptobenzothiazole with tert-Butylamine, highlighting a well-established chemical pathway for its production.
