IPTG is a BioScience-Grade inducer supplied at a minimum purity of 99 % and specified as dioxane-free and animal-free. With the empirical formula C₉H₁₈O₅S, a molar mass of 238,30 g/mol, CAS number 367-93-1 and EG number 206-703-0, it is a standard reagent for inducing lac operon–controlled expression systems in molecular biology. The material is A flash point above 110 °C is reported for the substance. IPTG is routinely used to trigger recombinant protein production in bacterial hosts and related reporter or screening setups. This grade from manufacturer Carl ROTH supports laboratories that require a defined, high-purity inducer without dioxane or animal-derived components. Clear analytical identity data aid documentation in research, method development and virus-related molecular work where controlled induction is required. size offers a practical working quantity for repeated induction experiments under established laboratory protocols.
