SECTION 10: Stability and reactivity

10.1Reactivity

no data available

10.2Chemical stability

Stable in light and air

10.3Possibility of hazardous reactions

4-HYDROXYPYRAZOLO(3,4-D)PYRIMIDINE is an amine derivative. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides. This chemical darkens above 572° F, and at an indefinite high temperature, it chars and decomposes. At 221° F, maximum stability occurs at pH 3.1- 3.4. This chemical decomposes in acidic and basic solutions.

10.4Conditions to avoid
