It's a rare compound, I don't have a standard of that, so HPLC, which is used more for routine samples would be rather useless.@janoshik - are you able to do an HLPC separation/quantification of Dimethylnandrolone Undecanoate? It has a number of stereocenters and I'd be interested in specific enantiomeric purity.
Mass spec or NMR is what I'd use. MS would be sufficient to determine purity in raw material, molecular mass and even wildly guess the molecular structure. Unfortunately mass spec can't determine isomers all that well, so if you're interested in enantiomeric purity you'd have to opt for NMR as well. My choice would be MS + NMR, but it gets much more expensive than routine testing quickly.
So, it is not a problem, but it'll cost more than regular routine testing.
