After finishing his dissertation about the quantitative separation of arsenic and antimony[1] in the works of Emil Fischer he got his doctoral degree.

Due to their extreme reactivity and flammability in air, boron hydrides could not be purified until his development of methods for separation using high-vacuum manifolds around 1912.

The hydrides of boron and silicon represented the first family of binary compounds to approach the richness of hydrocarbons in terms of structural diversity.

Boron hydrides such as diborane later developed into a range of reagents for organic synthesis as well as a source of diverse ligands and building blocks for researchers.

This method made beryllium available for industrial use, such as in special alloys and glasses and for making windows in X-ray tubes.

In his own words, he considered the system to be "simple, clear, immediately intelligible, capable of the most general application."

Nevertheless, a paper from Fleischmann, in which removal of mercury in amalgam-related illness had led to complete recovery, supported his idea.

A committee was founded in Berlin to investigate cases of possible mercury intoxication and hence the term micromercurialism was first used.

In recognition of his contributions to the field of inorganic chemistry, the German Chemical Society (Gesellschaft Deutscher Chemiker) created in 1950 the Alfred Stock Memorial Prize.

The prize, consisting of a gold medal and money, is awarded every other year for "an outstanding independent scientific experimental investigation in the field of inorganic chemistry.
