Description
Application
Squaric acid is a reagent for chemical synthesis used for instance to make photosensitive squaraine dyes and inhibitors of protein tyrosine phosphatases.
Purpose
For R&D use onlynot for drug household or other uses.
General Description
The conjugate base of squaric acid is the hydrogensquarate anion C4HO4 and the conjugate base of the hydrogensquarate anion is the divalent squarate anion C4O42. This is one of the oxocarbon anions which consist only of carbon and oxygen.
