Description

(E)-2-Methyl-2-Butenoic Acid (1As,1Aα,3Aα)-4α-[2-(2,5-Dihydro-5-Oxofuran-3-Yl)Ethyl]Decahydro-4,5α,7Aα,7Bα-Tetramethylnaphth[1,2-B]Oxiren-7β-Yl Ester is a high-purity, complex organic ester with a unique molecular architecture combining a tiglic acid moiety with a fused polycyclic system. This compound matters as a sophisticated chemical intermediate and research chemical for the synthesis of novel molecules with potential biological activity. It is primarily needed by pharmaceutical R&D laboratories, agrochemical innovators, and advanced fine chemical manufacturers.

Application

• Pharmaceutical Intermediate: Key building block for the research and development of novel active pharmaceutical ingredients (APIs), particularly in steroidal or complex polycyclic frameworks.
• Agrochemical Synthesis: Used in the creation of advanced crop protection agents and plant growth regulators requiring specific stereochemistry.
• Chemical Research: Serves as a valuable probe or starting material in academic and industrial research for studying structure-activity relationships (SAR) and developing new synthetic methodologies.
• Fine Chemical Production: Employed in the multi-step synthesis of specialty chemicals, flavors, fragrances, and advanced materials where its specific ester linkage and stereocenters are critical.
• Process Chemistry Development: Used for scaling up synthetic routes and optimizing reaction conditions in pilot plants for complex molecule manufacturing.

Quality Control

Our (E)-2-Methyl-2-Butenoic Acid Ester is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC, GC, NMR, and mass spectrometry, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided and can be tailored to meet specific customer or regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This material is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere); containers should be kept sealed under an inert gas (e.g., nitrogen or argon) when not in use to maintain product integrity. Keep away from heat, sparks, and open flame.
