N-tert-Butyl-2-benzothiazolesulfenamide

N-tert-Butyl-2-benzothiazolesulfenamide (CAS 95-31-8) is a sulfenamide-class accelerator known commercially as Vulkacit NZ, Santocure NS, Nocceler NS, and Accel BNS, and abbreviated as NTBBTS. It carries no assigned E-code. It is registered under EC 202-409-1 and classified within HS code 29342000.

In rubber and tire manufacturing, NTBBTS functions as a delayed-action vulcanization accelerator, activating sulfur crosslinking at processing temperatures to improve scorch safety and cure efficiency. It also demonstrates antimicrobial activity relevant to preservation applications in biotechnology contexts, and has documented use as a flavorant precursor in food and nutrition formulations.

NTBBTS is supplied in compliance with REACH registration requirements applicable to EU markets. Procurement teams should confirm grade specifications against intended application, as rubber-grade and specialty-grade material may differ in purity thresholds. Standard packaging formats follow supplier-specific conventions; buyers should request certificates of analysis and safety data sheets at point of inquiry.
