Do you have a more exact mass? Without some more digits it is impossible to tell for sure.
I have observed [M-CO2-C3H6] at 86.0368.
If you have exact mass you can use the Rdisop package for R to get an idea of the possibilities (http://www.bioconductor.org/packages/2. ... disop.html).
Like this:
decomposeMass(43.99, ppm=20, mzabs=0.01)
