Description

2,3,4-Furantriol, 5-(5-Ethyl-3-Isoxazolyl)Tetrahydro-, (3R,4S,5R)- (9Ci) is a high-purity, stereochemically defined heterocyclic compound with the CAS number 252760-75-1. This advanced chemical intermediate is valued for its unique molecular architecture, which makes it a critical building block in the synthesis of complex, biologically active molecules. It is primarily sought after by research institutions and pharmaceutical development companies engaged in medicinal chemistry and novel drug discovery programs.

Application

• Pharmaceutical Intermediate: Serves as a key chiral synthon in the research and development of new active pharmaceutical ingredients (APIs), particularly for central nervous system (CNS) and anti-infective drug candidates.
• Medicinal Chemistry Research: Used as a core scaffold or precursor for constructing complex heterocyclic libraries in high-throughput screening and structure-activity relationship (SAR) studies.
• Asymmetric Synthesis: Employed in stereoselective synthesis routes due to its defined (3R,4S,5R) configuration, enabling the production of enantiomerically pure compounds.
• Agrochemical Development: Acts as a potential intermediate in the synthesis of novel herbicides or fungicides with specific modes of action.
• Fine Chemical Production: Utilized in custom synthesis and contract manufacturing for producing specialized, high-value chemicals for research and development.

Quality Control

Every batch of 2,3,4-Furantriol, 5-(5-Ethyl-3-Isoxazolyl)Tetrahydro-, (3R,4S,5R)- (9Ci) is manufactured under strict quality management systems. Our products undergo rigorous quality testing, including chiral purity analysis and impurity profiling, to ensure compliance with research-grade standards. A comprehensive Certificate of Analysis (COA) detailing identity, purity (HPLC), chiral excess, and related substances is provided with each shipment to guarantee reproducible results for your critical research and development work.

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 compound is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation and moisture absorption.
