Description

n-(4-Hydroxybutyl)Acrylamide is a versatile bifunctional monomer featuring both a polymerizable acrylamide group and a terminal hydroxyl group. This unique structure makes it a valuable building block for synthesizing specialty polymers with tailored properties, such as enhanced hydrophilicity, adhesion, and crosslinking capability. It is primarily utilized in the production of advanced coatings, adhesives, hydrogel materials, and as a reactive intermediate in pharmaceutical and personal care applications.

Application

• Hydrogel Synthesis: A key monomer for creating hydrophilic, cross-linked polymer networks used in contact lenses, wound dressings, and controlled drug delivery systems.
• Advanced Coatings & Adhesives: Imparts improved adhesion, flexibility, and moisture resistance to industrial and specialty coatings, inks, and pressure-sensitive adhesives.
• Polymer Modification: Serves as a functional comonomer to introduce pendant hydroxyl groups into acrylic and vinyl polymer chains, enhancing solubility and reactivity for further chemical grafting.
• Personal Care Polymers: Used in the formulation of hair styling resins, skincare films, and other cosmetic ingredients where film-forming and moisturizing properties are desired.
• Chromatography Media: Employed in the manufacture of functionalized resins and beads for affinity chromatography and solid-phase synthesis.
• Bioconjugation & Pharmaceutical Intermediates: The hydroxyl group provides a handle for linking polymers to drugs, proteins, or other bioactive molecules.

Quality Control

Our n-(4-Hydroxybutyl)Acrylamide is manufactured under strict quality management protocols. Each batch is subjected to rigorous analytical testing, including chromatographic purity analysis and identity confirmation, to ensure it meets precise specifications for critical applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and compliance.

Storage

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