Description

cis-δ2-11-Methyl-Dodecenoic Acid is a specialized, unsaturated fatty acid derivative characterized by its unique cis-configuration and methyl branch at the C11 position. This structural specificity makes it a valuable intermediate for synthesizing high-performance lubricants, advanced polymers, and fine chemicals where precise molecular architecture is critical. It is particularly sought after by R&D chemists and process engineers in the specialty chemical, pharmaceutical intermediate, and advanced material sectors.

Application

• Pharmaceutical Intermediate: Serves as a key chiral building block for the synthesis of bioactive molecules and active pharmaceutical ingredients (APIs).
• Specialty Polymer Synthesis: Used as a monomer or co-monomer to introduce specific branching and unsaturation into polymers, enhancing properties like flexibility and thermal stability.
• Advanced Lubricant Formulations: Acts as a precursor for synthetic ester base oils and additives, contributing to improved viscosity indices and low-temperature performance.
• Fragrance and Flavor Chemistry: Employed in the creation of complex macrocyclic musks and other specialty aroma chemicals due to its specific carbon chain length and functional group.
• Agrochemical Synthesis: Utilized in the production of specialized surfactants and plant growth regulators.
• Research & Development: A valuable tool in organic synthesis and chemical biology for studying structure-activity relationships and developing new synthetic methodologies.

Quality Control

Every batch of cis-δ2-11-Methyl-Dodecenoic Acid is produced and tested under a strict quality management system to ensure consistency and purity for your critical applications. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, isomeric purity, and impurity profiles. Our quality commitment aligns with cGMP principles where applicable, and we support compliance with global regulatory frameworks like REACH.

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. Due to its easily oxidized nature, minimize headspace and exposure to air after opening.
