ISO 9001:2015 & ISO 14001:2015 certified · Supplying laboratories and industry since 2000 · Certificate of Analysis with every batch

Denatonium benzoate granules are a highly bitter, non-toxic compound used as a denaturant in industrial and consumer products to deter ingestion, such as in antifreeze, cleaning agents, and pharmaceuticals. This bittering agent is classified as extremely bitter, with a detection threshold as low as 0.000000001% in water. Catalogue details include CAS 3734-33-6, molecular formula C21H29N2O·C7H5O2, and a molecular weight of 446.58. It is stable at ambient storage conditions but carries a "Danger" signal word due to its severe eye and skin irritation hazards. Molekula supplies Denatonium benzoate granules from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
