Application

Pyrithiamine hydrobromide can be used as a precursor for the synthesis pyrithiamine pyrophosphate.

General description

Pyrithiamine hydrobromide is a heterocyclic building block that is used as a valuable tool in organic synthesis and medicinal chemistry due to its ability to mimic thiamine deficiency and its potential for the development of new compounds with useful pharmacological properties.
