Description

2-Methyl-3-Buten-2-Ol is a highly versatile, branched-chain unsaturated alcohol with significant industrial utility. Its reactive hydroxyl and olefinic groups make it a valuable chemical intermediate for synthesizing more complex molecules, including fragrances, pharmaceuticals, and agrochemicals. This compound is particularly sought after by manufacturers in the flavor & fragrance, pharmaceutical, and specialty chemical sectors for its unique structural properties.

Application

• Fragrance and Flavor Ingredient: Serves as a key building block in the synthesis of terpene-like aroma chemicals and flavor compounds.
• Pharmaceutical Intermediate: Used in the production of active pharmaceutical ingredients (APIs) and other fine chemicals due to its reactive functional groups.
• Agrochemical Synthesis: Acts as a precursor in the manufacture of certain pesticides, herbicides, and plant growth regulators.
• Polymer and Resin Modifier: Employed in the creation of specialty polymers, where it can introduce branching or cross-linking sites.
• Organic Synthesis Reagent: A valuable reagent in laboratory and industrial-scale organic chemistry for constructing carbon chains.
• Solvent and Coalescing Agent: Finds use in specialty coating formulations and as a solvent for specific resins.

Quality Control

Our 2-Methyl-3-Buten-2-Ol is produced under stringent quality management systems. Every batch undergoes rigorous analytical testing, including GC and HPLC analysis, to ensure high purity and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, identity, and impurity profiles to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and ignition points. Due to its highly volatile nature, containers must be kept tightly sealed when not in use to prevent evaporation and concentration changes. Recommended storage temperature is 2-8°C for extended stability, though short-term storage at controlled room temperature (15-25°C) is acceptable.
