If you are referring to DEF, it's all the same no matter what brand. Formulation is constant across the board. Deionized, purified water and Urea in solution. It does have a shelf life so one needs to check the useable date.
I buy expired dated DEF from my lubricant supplier and mix it with water and spray it on my hayfields as a foliar innoculant. Fertilizer is fertilizer and urea in solution can be used in plant uptake by direct methods.
It all has a blue tint. That comes about by the solution urea. Urea imparts a light blue tint.
