Sourcing High-Quality PDE5 Inhibitor Raw Powder

PDE5 inhibitors are among the most widely prescribed pharmaceutical compounds globally. Sourcing high-purity API raw powder from a certified manufacturer is critical for pharmaceutical formulation and regulatory compliance.

1. Purity Standards for PDE5 Inhibitor APIs

AASchem ensures quality through a Double Verification System:

HPLC Analysis: Main peak area ≥99.0% for Tadalafil, ≥99% for Sildenafil Citrate. No single impurity exceeds 0.10%.
MS (Mass Spectrometry): Confirms molecular structure and molecular weight, ensuring compound identity.

2. Industrial Applications

Our PDE5 inhibitor API powders are intended for pharmaceutical manufacturing and research:

Pharmaceutical Formulation: Production of oral tablets, capsules, and oral jelly formulations.
Reference Standards: Analytical calibration for QC laboratories.
Bioequivalence Studies: In-vitro dissolution and pharmacokinetic research.

3. Handling and Storage

PDE5 inhibitor powders are generally stable but require proper storage:

Temperature: Store at room temperature (15°C–25°C). Avoid excessive heat.
Moisture: AASchem uses double-layer aluminum foil bags with desiccants. Sildenafil Citrate is particularly hygroscopic.
Light: Protect from direct UV exposure to prevent degradation.
