Description

3-Acrylamido-3-Methylbutyric Acid is a versatile bifunctional monomer featuring both a polymerizable acrylamide group and a carboxylic acid functionality. This unique structure makes it a critical building block for synthesizing advanced polymers with tailored properties, such as specific charge densities, pH-responsiveness, and enhanced adhesion. It is essential for R&D and production chemists in the specialty polymer, pharmaceutical intermediate, and advanced material sectors seeking to innovate with custom acrylic resins, hydrogels, and functional coatings.

Application

• Specialty Polymer Synthesis: Key monomer for producing acrylic copolymers with carboxyl functionality for use in dispersants, superplasticizers, and rheology modifiers.
• Hydrogel Manufacturing: Used in the formulation of pH-sensitive or ionic hydrogels for biomedical applications, including drug delivery systems and wound dressings.
• Adhesive & Coating Resins: Incorporated into polymer backbones to improve adhesion to polar substrates and to introduce cross-linking sites via the carboxylic acid group.
• Pharmaceutical Intermediates: Serves as a precursor in the synthesis of more complex molecules for pharmaceutical research and development.
• Personal Care Polymers: Utilized in the production of hair fixatives and skincare polymers where film-forming and conditioning properties are required.
• Ion-Exchange Resins: A functional monomer for creating weak acid cation exchange resins used in water treatment and purification processes.

Quality Control

Our 3-Acrylamido-3-Methylbutyric Acid is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the exacting standards required for polymer and pharmaceutical applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to guarantee reliable performance in your formulations.

Storage

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