Description

Amylose Triacetate is a high-purity, fully acetylated derivative of the linear starch polymer amylose. This compound is valued for its excellent film-forming properties, biodegradability, and utility as a model substrate for enzymatic studies. It serves as a critical material for researchers and manufacturers in the biopolymer, pharmaceutical, and specialty chemical sectors seeking consistent, high-quality carbohydrate derivatives.

Application

• As a model substrate for studying the activity and kinetics of amylase enzymes in biochemical and pharmaceutical research.
• In the development of specialty films and coatings with tailored permeability and biodegradability for packaging applications.
• For the fractionation and purification of complex carbohydrate mixtures in analytical and process chemistry.
• As a starting material or intermediate in the synthesis of more complex, functionalized starch derivatives.
• In controlled-release drug delivery systems where its solubility profile can be leveraged for targeted release.
• For creating chromatographic media and separation membranes used in laboratory and industrial-scale purification processes.

Quality Control

Our Amylose Triacetate is produced and tested under a stringent quality management system to ensure batch-to-batch consistency and reliability. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing key parameters such as degree of substitution, acetyl content, viscosity, and purity. We adhere to relevant industry standards and our QC protocols are designed to meet the exacting requirements of research and industrial applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance.
