Description

2,4-Pentadienoic Acid, 5-(1-Hydroxy-2,6,6-Trimethyl-4-Oxo-2-Cyclohexen-1-Yl)-3-Methyl-, Methyl Ester, [S-(Z,E)]- is a high-purity, stereochemically defined chemical intermediate of significant interest in advanced organic synthesis. This compound matters for its role as a key building block in the production of complex molecules, particularly in the fragrance, flavor, and pharmaceutical sectors, where precise stereochemistry is critical for bioactivity and sensory properties. It is primarily needed by R&D chemists and process development teams in fine chemical, agrochemical, and specialty ingredient manufacturing.

Application

• Fragrance and Flavor Intermediate: Serves as a crucial precursor in the synthesis of complex terpenoid and ionone-based aroma chemicals, contributing to woody, floral, and fruity notes.
• Pharmaceutical Research: Used as a sophisticated building block for constructing chiral centers and complex ring systems in the development of novel active pharmaceutical ingredients (APIs).
• Agrochemical Synthesis: Employed in the research and production of advanced crop protection agents that require specific stereoisomers for optimal efficacy.
• Fine Chemical Manufacturing: Acts as a specialized intermediate for custom synthesis and contract manufacturing of high-value, low-volume specialty chemicals.
• Academic and Industrial R&D: Utilized in methodological studies and the exploration of new synthetic pathways in organic chemistry due to its reactive diene and ester functionalities.

Quality Control

Our 2,4-Pentadienoic Acid derivative is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including chiral HPLC and NMR, to ensure high stereochemical purity and chemical identity. Certificates of Analysis (COA) detailing purity, isomeric composition, and impurity profiles are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at controlled room temperature (15-25°C) in a cool, dry, and well-ventilated place. This material is light-sensitive and easily oxidized; prolonged exposure to air, light, or elevated temperatures should be avoided to maintain stability and purity.
