Theophylline Chemical Properties,Uses,Production

Chemical Properties

white to light yellow crystal powder

Uses

Xanthine derivative with diuretic, cardiac stimulant and smooth muscle relaxant activities; isomeric with theobromine. Small amounts occur in tea. Bronchodilator.

Definition

ChEBI: A dimethylxanthine having the two methyl groups located at positions 1 and 3. It is structurally similar to caffeine and is found in green and black tea.

General Description

Odorless white crystalline powder. Odorless. Bitter taste.

Air & Water Reactions

Slightly soluble in water.

Reactivity Profile

Theophylline neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.

Fire Hazard

Flash point data for Theophylline are not available, however Theophylline is probably combustible.

Biological Activity

Bronchodilator, anti-inflammatory and immunomodulator. Antagonizes adenosine receptors and is a weak non-selective inhibitor of phosphodiesterases (PDEs).
