Can I dilute agricultural vinegar for pickling?

I have a 45% vinegar, specifically this one, that I've been using to kill weeds in my yard. Having 1 jug like this could save me a lot of space where I don't have much storage. It doesn't say food grade safe on it. Is only 5% vinegar from the store approved for canning?

Reading online it says not to dilute vinegar in general. But it does not say if using an agricultural vinegar like this one is safe for human consumption.
