Description

Carbamic Acid, (2,5-Dihydroxypentyl)-, 1,1-Dimethylethyl Ester (9Ci) is a specialized carbamate derivative characterized by its unique dihydroxypentyl side chain and tert-butyl ester protecting group. This compound is significant as a versatile synthetic intermediate, offering a reactive carbamate functionality that is crucial for constructing more complex molecular architectures in advanced organic synthesis. It is primarily needed by research and development chemists in the pharmaceutical and agrochemical industries for applications such as peptide mimetics, prodrug development, and the synthesis of active pharmaceutical ingredients (APIs).

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel drug candidates, particularly in the development of protease inhibitors and other enzyme-targeted therapies.
• Prodrug Synthesis: Utilized in the design and preparation of prodrugs, where its carbamate group can be cleaved in vivo to release an active drug molecule.
• Peptidomimetics Research: Serves as a scaffold or backbone component in the creation of peptide mimetics to enhance metabolic stability and bioavailability.
• Agrochemical Development: Intermediate in the synthesis of advanced herbicides, fungicides, or insecticides that require carbamate chemistry.
• Polymer Science: Potential monomer or cross-linking agent for producing specialty polyurethanes or functional polymers with pendant hydroxyl groups.
• Chemical Biology Tool: Used in the synthesis of activity-based probes or affinity labels for studying enzyme function and mechanism.

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). This product is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed and under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent degradation. Keep away from heat and incompatible materials.
