Description

2-Buten-1-Ol, 2-Methyl-, (E)- is a valuable unsaturated alcohol intermediate with a defined stereochemistry. Its primary commercial value lies in its role as a versatile building block for synthesizing fine chemicals, flavors, fragrances, and pharmaceutical active ingredients. This product is essential for R&D laboratories and manufacturers in the agrochemical, flavor & fragrance, and specialty chemical industries seeking high-purity intermediates for complex synthesis.

Application

• Flavor and Fragrance (F&F) Intermediate: Serves as a key precursor in the synthesis of various esters and aldehydes used to create fruity, green, or floral notes.
• Pharmaceutical Synthesis: Used as a chiral building block in the production of specific active pharmaceutical ingredients (APIs) and other bioactive molecules.
• Agrochemical Manufacturing: Acts as an intermediate in the synthesis of certain pesticides, herbicides, and plant growth regulators.
• Specialty Polymer Chemistry: Utilized in the production of specialty monomers or cross-linking agents due to its reactive hydroxyl and alkene functional groups.
• Organic Synthesis Research: A valuable reagent for academic and industrial R&D in developing new synthetic methodologies and complex organic compounds.
• Production of Plasticizers and Stabilizers: Can be used to manufacture derivatives that function as additives in polymer formulations.

Quality Control

Our 2-Buten-1-Ol, 2-Methyl-, (E)- is produced and tested under a strict quality management system. We ensure high chemical purity and isomeric integrity through advanced analytical techniques including GC, HPLC, and NMR. A comprehensive Certificate of Analysis (COA) detailing identity, purity (assay), specific isomer content, and impurity profiles is provided with each batch to guarantee consistency and support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place. Recommended storage temperature is 2-8°C to minimize oxidation and polymerization. Keep away from heat, sparks, open flames, and strong oxidizing agents.
