derivatization for GC-MS
« on: December 28, 2005, 08:33:35 AM »
Hi,

can anybody  give detailed information on derivatizing a natural product sample with diazomethane, and purification procedures for side products etc... which I need for the GC-MS analysis.

thanks in advance

This is highly dependant on the sample, diaztisation is used as a derivitising agent for many functional groups to increase their volitility and/or stability under GC analysis. What is the sample comprised of?

Whats the Molecular Weight? Why can't you use GC-MS?
Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex
