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.

Where is Ammonium sulfide used?

• Food and flavor manufacturing: FEMA 2053-listed flavoring agent for roasted, meaty or savory profiles in processed foods
• Flavor houses: incorporated into reaction flavor systems
• During thermal processing, controlled sulfur release generates target aroma compounds.
• Agriculture: nitrogen and sulfur source in specialty fertilizers for sulfur-deficient soils
• Chemical synthesis: reagent for controlled introduction of sulfide ions

Commercial specifications

• Aqueous solution, concentration typically 40–44% in commercial grades
