Denatonium benzoate granules are a highly bitter 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 because it causes serious eye damage (H318), and it is also harmful if swallowed or inhaled. Molekula supplies Denatonium benzoate granules from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
