1-Heptanol (n-Heptyl Alcohol) 99% / ≥99.5% / 99.8% CAS No. 111-70-6 Industrial & Pharmaceutical Grade

1-Heptanol, available in 99%, ≥99.5%, and 99.8% concentrations, is produced via advanced hydroformylation of 1-hexene followed by hydrogenation, or through the reduction of heptanal . As a bio-based version, it can also be processed from renewable castor oil, offering a 100% linear, carbon-neutral alternative for sustainable applications . It features excellent solvency power, slow evaporation rate, and a characteristic oily, fatty, green, winey odor reminiscent of柑橘 and gardenia . As a straight-chain primary alcohol with a seven-carbon chain, it is widely used as a solvent, a fragrance and flavor intermediate, a chemical building block for plasticizers and surfactants, and a reagent in biochemical research . Its high purity and consistent quality make it ideal for critical applications requiring precise solvent properties. Each batch is rigorously tested using GC analysis to ensure consistent quality meeting industrial, pharmaceutical, and food-grade standards .

Scope of Application

Used as a solvent in industrial coatings, paints, and printing inks, providing excellent flow and leveling properties due to its slow evaporation rate .
Acts as a key intermediate in the fragrance and flavor industry for the synthesis of aromatic chemicals, such as γ-decalactone (peachy character) and various esters (from C1 to C8 acids) that impart green, floral, or fruity notes .
Widely applied in cosmetic formulations as a chemical intermediate to produce ingredients with a natural origin, including emollients and surfactants . It has a degree of Natural Origin per ISO16128 and conforms to the COSMOS Standard .
Serves as a chemical intermediate in the manufacturing of phthalate-free plasticizers for the plastics industry .
Functions as a reagent in biochemical research, including studies on membrane structure, enzyme activity, and as a solvent for hydrophobic compounds in various assays .
Used in the production of surfactants for detergents and cleaning products, improving their ability to break down oils and dirt .
