Skatole 3-methylindole is soluble in alcohol. I would assume this is Methyl alcohol.
When this is reported without qualifiers, it usually means ethanol. However, for many things, not everything but many thingsmethanol, ethanol, isopropanol solubility is the same.
Does it have to be pure or can a lower purity of alcohol be used ?
Impure with what? Water? Gasoline? Dirt?
Can it be denatured ?
Probably the best choice, pure ethanol is expensive. There's no such thing as denatured methanol.
What is the max solution ratio, dry skatole to alcohol for 100% strength ? Thanks
What strength is needed for your application? Often, the same reference that tells you solubility, tells you how soluble it is.
By the way, anyone can Google for the nature of skatole. It smells like ... no, it is the smell of s#*$. Care to trouble us with what your application is?
