Diprophylline

Synonymes : 7-(2,3-Dihydroxypropyl)theophylline, Diprophylline, Dyphylline, Glyceryl theophylline, 479-18-5

Diprophylline (CAS 479-18-5) is a xanthine derivative supplied as a white to off-white crystalline powder. Unlike theophylline, it is not metabolized to caffeine or theophylline in the body, which gives it a distinct pharmacokinetic profile. We stock it as a high-purity API grade with an assay of ≥99.0% by HPLC, suitable for pharmaceutical formulation and research use.

Buyers typically source Diprophylline for bronchodilator and respiratory care products, where it is formulated into tablets, capsules, and injectable solutions. Its good water solubility makes it a practical candidate for liquid dosage forms and oral solutions. The material is also used as a reference standard in analytical laboratories and as a building block in chemical synthesis.

We supply Diprophylline under strict quality control, with each batch accompanied by a Certificate of Analysis. The product is manufactured in FDA-inspected facilities and is available for immediate shipment from stock. For custom requirements, please contact our sales team.

Applications & Formulation Use

Diprophylline is primarily used in the formulation of bronchodilator medications for respiratory conditions such as asthma and COPD. It is commonly incorporated into immediate-release tablets and capsules, and because of its high aqueous solubility, it is also suited for oral solutions and syrups. In injectable preparations, it is used in hospitals and clinics for acute bronchospasm management.

Beyond finished dosage forms, Diprophylline serves as a reference standard in analytical method development and quality control laboratories. It is also employed as an intermediate in the synthesis of more complex xanthine derivatives. Formulators value its stability and compatibility with common excipients, which simplifies product development.

Sourcing & Production

Diprophylline is produced through the reaction of theophylline with 3-chloropropane-1,2-diol under controlled conditions. The crude product is then purified by recrystallization to achieve the required purity. Our manufacturing partners operate under GMP conditions and adhere to strict quality standards to ensure consistent quality from batch to batch.

The final product is a white to off-white crystalline powder, packaged in fiber drums with double polyethylene liners to protect against moisture and contamination. Each batch is tested for identity, assay, and physical properties before release.
