It is practically insoluble in water, freely soluble in dichloromethane and in dioxan, sparingly soluble in ether and slightly soluble in methyl alcohol.

According to Heller's and other contemporary descriptions, urostealith is a soft brown substance, insoluble in water, sparingly soluble in ether.

The liberated nitric oxide is sparingly soluble in water and returns to the gas in the chamber where it reacts with oxygen in the air to reform nitrogen dioxide.
24.
The base is both very hydrophilic and very lipophilic and can be recovered easily and almost completely from reaction mixtures by the formation of the sparingly soluble tetrafluoroborate salt.

*8-Hydroxyquinoline ( Oxine ), ( C9H6ON ) forms sparingly soluble derivatives with metallic ions, colorless, crystalline solid, and m . p . 75-76.
26.
Chromium ( II ) fluoride is sparingly soluble in water, almost insoluble in alcohol, and is soluble in boiling hydrochloric acid, but is not attacked by hot distilled sulfuric acid or nitric acid.
27.
Compounds such as thiocyanate and thiosulfate enhance solubility when they are present in a sufficiently large quantity, due to formation of highly soluble complex ions, but they also significantly depress solubility when present in a very small quantity, due to formation of sparingly soluble complex ions.
28.
Certainly Zingerone is a crystalline solid that is sparingly soluble in water, but soluble in ether, however when synthesised and tasted does not have any pungency, which suggests it is more likely that zingerone is a decomposition product of, rather than the direct source of the pungency of ginger.

They interpreted this as meaning that to pass the cell membrane a molecule must be at least sparingly soluble in oil, their lipoid theory of narcosis . Based on this evidence and further experiments, they concluded that the cell membrane might be made of lecithin ( phosphatidylcholine ) and cholesterol.
