Description

Mil-101(Cr)-So3H CAS NO 1331961-41-1 is a sulfonated derivative of the chromium-based metal-organic framework MIL-101(Cr), engineered to introduce strong Brønsted acid sites onto its highly porous structure. This functionalization is critical for enhancing catalytic activity and selectivity in demanding acid-catalyzed reactions. It is an essential advanced material for researchers and process engineers in the chemical, petrochemical, and pharmaceutical industries seeking efficient, heterogeneous acid catalysts.

Application

• Heterogeneous Acid Catalysis: Used as a solid acid catalyst for esterification, transesterification (e.g., biodiesel production), and condensation reactions, offering easy separation and reusability.
• Biomass Conversion: Catalyzes the dehydration of sugars (like fructose to 5-hydroxymethylfurfural) and other biomass-derived feedstocks into valuable platform chemicals.
• Fine Chemical Synthesis: Facilitates Friedel-Crafts alkylation and acylation, acetalization, and other organic transformations under milder conditions.
• Gas Storage & Separation: Leverages its intrinsic high surface area and porosity, potentially enhanced by sulfonic groups, for selective adsorption and separation processes.
• Proton Conduction: Serves as a promising filler material in proton exchange membranes for fuel cells due to the presence of sulfonic acid groups.
• Environmental Remediation: Applied in the adsorption and catalytic degradation of organic pollutants from wastewater.
• Drug Delivery Carrier: Explored for the controlled release of therapeutic agents, where the acidic functional groups can enable pH-responsive behavior.
• Sensor Development: Utilized as a sensitive platform for detecting various analytes due to its modifiable surface chemistry and porous structure.

Quality Control

Our Mil-101(Cr)-So3H is produced and tested under strict quality management protocols. Each batch is characterized to ensure consistent porosity, acid site density, and catalytic performance. Comprehensive analytical data, including XRD for phase purity, BET for surface area, and titration for acid capacity, are documented. A Certificate of Analysis (COA) is provided with every shipment to guarantee specification compliance.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store in a cool, dry place, ideally under an inert atmosphere (e.g., nitrogen or argon) to maintain catalytic activity and structural integrity. Recommended storage temperature is 2-8°C for long-term stability.
