TDA Reagent is a corrosive inorganic reagent used in microbiology to detect tryptophan deaminase (TDA) and phenylalanine deaminase activity, for example with API 20E identification strips, where it forms a coloured complex with indolepyruvic acid. It consists of iron(III) chloride, hydrochloric acid, and water. Available in various grades with CAS number 7647-01-0, it is stored at ambient temperatures and labeled with the signal word Danger due to its corrosive nature. Molekula supplies TDA Reagent from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
