Dibenzyl disulfide

Dibenzyl disulfide (CAS 150-60-7, EC 205-764-0, formula C14H14S2) is an organosulfur compound also known as benzyl disulfide or benzyl bisulfide, and registered under FEMA 3617. It carries no E-code designation. It is supplied as a neat chemical under HS code 29309090.

In food and flavor applications, dibenzyl disulfide contributes characteristic roasted, meaty, and alliaceous notes by releasing reactive sulfur species during thermal processing. In polymer and petroleum chemistry, it functions as a sulfur-donor catalyst and antioxidant, where its disulfide bond undergoes homolytic cleavage to generate stabilizing radical intermediates. Antimicrobial activity has also been documented in personal care formulations.

Dibenzyl disulfide is available in food-grade quality conforming to FEMA 3617 specifications, and is subject to REACH registration requirements for supply within the European Economic Area. Procurement teams should confirm lot-specific purity documentation and packaging format directly with the supplier, as specifications may vary by grade.
