    This will be of interest to the formulators, manufacturing and CMC scientists: "FDA and international regulators developed a methodology, the Carcinogenic Potency Categorization Approach (CPCA), that uses the chemical structure of a nitrosamine impurity to recommend AI limits by assignment to 1 of 5 predicted potency categories reflecting carcinogenic risk".  The FDA recently posted the details on this:

    Development of the Carcinogenic Potency Categorization Approach

    Based on a publication: Development and application of the Carcinogenic Potency Categorization Approach (CPCA). Regul Toxicol Pharmacol, 150:105640. https://doi.org/10.1016/j.yrtph.2024.105640
