Description

Poly-o-Acetylserine is a synthetic polymer derived from the amino acid serine, where the hydroxyl groups are acetylated. This modification imparts unique solubility and reactivity profiles, making it a valuable intermediate for advanced material synthesis and biochemical research. It is particularly sought after by manufacturers in the pharmaceutical and specialty chemical sectors for developing drug delivery systems, biodegradable polymers, and functional biomaterials.

Application

• Pharmaceutical Intermediate: Used in the synthesis of novel drug conjugates and prodrugs to enhance bioavailability and targeting.
• Biomedical Material Research: Serves as a key building block for creating biodegradable scaffolds, hydrogels, and tissue engineering matrices.
• Polymer Chemistry: Acts as a precursor for developing specialty poly(amino acid)s and functional polymers with tailored properties.
• Cosmetic & Personal Care Formulations: Employed in the development of advanced, skin-compatible film formers and delivery agents for active ingredients.
• Bioconjugation & Protein Engineering: Utilized as a linker or modifier in the site-specific modification of peptides and proteins.
• Analytical & Diagnostic Reagents: Functions as a component in the preparation of standards and reagents for biochemical assays.

Quality Control

Our Poly-o-Acetylserine is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent molecular weight distribution, purity, and acetyl content. Certificates of Analysis (COA) detailing specifications such as NMR, FTIR identification, and residual solvent levels are provided with every shipment to guarantee compliance with your research and production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption, which can affect product stability and performance.
