Description

4-o-Methyl-D-Glucurono-D-Xylan-Remazol B CAS NO 9062-57-1 is a chemically modified xylan derivative, specifically a glucuronoxylan conjugated with the reactive Remazol B dye. This compound is significant as a specialized biochemical tool and a model substrate for studying hemicellulose structure and enzymatic degradation. It is primarily needed by researchers and industrial laboratories in the fields of biomass analysis, pulp and paper chemistry, and enzyme characterization, particularly for investigating xylanase and glucuronidase activities.

Application

• Biochemical Research: Used as a specific, chromogenic substrate for the assay and kinetic study of endo-xylanases and α-glucuronidases.
• Enzyme Characterization: Essential for determining the activity, specificity, and mode of action of hemicellulolytic enzymes in academic and industrial R&D.
• Biomass Conversion Studies: Serves as a model compound to simulate and analyze the enzymatic breakdown of glucuronoxylan, a major component of hardwood hemicellulose.
• Pulp and Paper Industry R&D: Employed in research focused on improving bleaching processes and understanding lignin-carbohydrate complexes.
• Quality Control in Enzyme Production: Acts as a standard substrate for the quality assurance of commercial enzyme preparations targeting hemicellulose.
• Biofuel Research: Utilized in studies aimed at optimizing the pre-treatment and enzymatic saccharification steps for bioethanol production from lignocellulosic materials.

Quality Control

Our 4-o-Methyl-D-Glucurono-D-Xylan-Remazol B is produced and handled under strict quality protocols to ensure batch-to-batch consistency and performance as a research substrate. Each lot is tested to confirm its suitability for enzymatic assays. Certificates of Analysis (COA) detailing specific parameters are available upon request to support your research and quality documentation needs.

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 (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent absorption of moisture, which may affect performance.
