Description

(1As,7R,7Ar,10As,11As)-1A,2,3,7A,8,10A,11,11A-Octahydro-11A-Methyl-8-Methylene-5H-7,4-Methenofuro[3,2-C]Oxireno[F]Oxacycloundecin-5,9(7H)-Dione is a complex, high-purity organic compound with a unique polycyclic structure containing fused furan and oxirene rings. This compound serves as a critical advanced pharmaceutical intermediate (API) and a versatile scaffold for synthetic organic chemistry research. It is primarily sought by R&D and process development teams in the pharmaceutical, agrochemical, and specialty chemical industries for the synthesis of novel active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of complex drug candidates, particularly those targeting neurological or anti-inflammatory pathways.
• Agrochemical Research: Used as a precursor in developing new generations of herbicides or insecticides with novel modes of action.
• Organic Synthesis Scaffold: Serves as a sophisticated starting material or intermediate in academic and industrial laboratories for constructing complex molecular architectures.
• Material Science Precursor: Potential use in the development of specialty polymers or advanced organic electronic materials due to its rigid, fused-ring system.

Quality Control

Every batch of our (1As,7R,7Ar,10As,11As)-1A,2,3,7A,8,10A,11,11A-Octahydro-11A-Methyl-8-Methylene-5H-7,4-Methenofuro[3,2-C]Oxireno[F]Oxacycloundecin-5,9(7H)-Dione is manufactured under strict quality management systems. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request.

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). Due to its sensitivity, the container should be kept under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation. Keep away from heat, sparks, and open flame.
