Acetonitrile stability

[Rick]

Hi!
I'm working with acetonitrile for pesticide analysis, but, sometimes, a degradation product from acetonitrile react with some of my pesticide (diclofluanid, tolyfluanid)
I want to stabilize my acetonitrile....i know that JT Baker sell a ultra grade acetonitrile with stabilizer but it is very expensive...
Do you know what is the stabilizer use for acetonitrile????
Thank you!

If you have questions about the suitability of solvents for your application, call the manufacturer's technical support. I have had good luck in getting answers from B&J (800-368-0050, don't know if # works in Canada). JT Baker has similar help but I don't have the number handy.
