3-Hydroxy-4-nitrobenzaldehyde Mass spec
« on: March 07, 2016, 12:41:00 PM »
Hey there, If the mass spec shows the molecular ion peak for 3-Hydroxy-4-nitrobenzaldehyde at 167, and the base peak at 137, what is the fragment structure that causes the base peak?
Thanks x

NIST spectrum shows base peak at M-1.
