Description

Alzamer CAS NO 81984-52-3 is a specialized polymer excipient widely recognized for its utility in advanced drug delivery systems. Its primary value lies in its ability to modulate the release profile of active pharmaceutical ingredients, enhancing therapeutic efficacy and patient compliance. This compound is essential for formulators and R&D scientists in the pharmaceutical and biotechnology industries seeking to develop controlled-release, enteric-coated, or targeted drug formulations.

Application

• As a key polymer for controlled-release matrix tablets and capsules.
• In the formulation of enteric coatings to protect APIs from gastric fluid.
• For developing targeted drug delivery systems, including microspheres and nanoparticles.
• As a film-forming agent and binder in pharmaceutical granulation processes.
• In cosmetic applications for sustained-release of active ingredients.
• As a component in specialty adhesive and coating formulations for medical devices.

Quality Control

Our Alzamer is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets the high-purity standards required for pharmaceutical applications. Certificates of Analysis (COA) documenting key parameters such as assay, viscosity, and residual monomers are available upon request. Production can adhere to relevant pharmacopeial standards (e.g., USP/NF, Ph. Eur.) based on customer requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after initial use to minimize moisture absorption.
