Description

1,4,8-Trihydroxy-2,3,4,9-tetrahydro-3-methyl-7-[4,8,9a-trihydroxy-1,2,3,4,9,9a-hexahydro-3-methyl-9,11-dioxo-1,4a-(epoxymethano)-4aH-xanthen-7-yl]-9-oxo-4aH-xanthene-4a-carboxylic acid methyl ester is a complex, high-purity xanthene derivative of significant interest in advanced chemical synthesis. This compound serves as a critical specialty intermediate for the development of novel active pharmaceutical ingredients (APIs) and sophisticated organic materials. It is primarily sought by pharmaceutical R&D teams, fine chemical manufacturers, and research institutions engaged in cutting-edge organic chemistry and medicinal chemistry projects.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of novel, complex drug candidates, particularly in oncology and anti-infective research.
• Medicinal Chemistry Research: Used as a core scaffold or precursor for structure-activity relationship (SAR) studies and lead optimization.
• Fluorescent Probe Development: Potential precursor for specialized dyes and probes due to its xanthene-based polycyclic structure.
• Organic Synthesis: Serves as a challenging and valuable substrate for developing new synthetic methodologies and catalytic processes.
• Academic & Industrial R&D: Employed in research programs focused on natural product synthesis, photochemistry, and material science.

Quality Control

Our production of this specialty chemical adheres to strict quality management systems. Every batch undergoes comprehensive analytical characterization using techniques including HPLC, NMR, and mass spectrometry to confirm identity and purity. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting critical quality attributes. We support cGMP compliance for pharmaceutical applications and can tailor specifications to meet specific project requirements.

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 light-sensitive and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat and incompatible materials.
