Ammonium sulfide

Ammonium sulfide ( CAS 12135-76-1 ), also known as diammonium sulfide, is a sulfur-containing ammonium salt used commercially as a flavoring agent and chemical intermediate. It contributes characteristic savory and sulfurous notes that replicate naturally occurring flavor profiles.

In food and flavor manufacturing, it is used as a FEMA 2053 -listed flavoring agent to develop roasted, meaty, or savory taste profiles in processed food products. Flavor houses incorporate it into reaction flavor systems.

During thermal processing, controlled sulfur release generates target aroma compounds essential for authentic food profiles. In agriculture, it functions as a nitrogen and sulfur source in specialty fertilizer formulations targeting sulfur-deficient soils.

It also serves as a reagent in chemical synthesis where controlled introduction of sulfide ions is required. Ammonium sulfide is supplied primarily as an aqueous solution, with concentration typically ranging from 40–44% in commercial grades.

Food-grade material is available in compliance with FEMA designation requirements for flavoring applications. Technical-grade solution is also offered for agricultural and industrial use cases to meet specific manufacturing needs.

Our product meets rigorous quality benchmarks to ensure consistency across batches. We provide documentation for FCC and other relevant standards to support your regulatory compliance and quality assurance protocols.
