Multiple methods for the preparation of 3,5-dibromopyrazole are described. While 3,5-dibromopyrazole is readily available on a kilogram scale, an internal demand facilitated the need to expand the vendor pool, with an overall goal of lowering cost. To pursue this goal, we focused on developing synthetic methods in the operating temperature range of −20 to 120 °C to remove production process constraints
