Hi ..., it would be really nice if someone has original research data on the Kovats Retention index of 4-Methyl-2-oxovaleric acid.
I already checked NIST Chemical Webbook, but chromatographic data are not available for 4-Methyl-2-oxovaleric acid?
GC-Column: DB-5 (5%-Phenyl)-methylpolysiloxane ); 60 m; Temperature ramp
Thanks in advance,
Marco
Hi Marco,
I know that Welke et al. have determined 4-methyl-2-oxovaleric acid on a polar DB wax column (doi:10.1016/j.chroma.2012.01.002).
They have also tested other column combinations such as DB-5×DB-WAX. Maybe they can help you.
Best regards
Philipp
Hi Marco,
You can also check the golm DB or the hmdb. In the latter there was a reference to Mona

1206 for 1TMS 1MeOx.
