Description

(1R)-(-)-Neoisocarvomenthol CAS NO 1126-41-6 is a high-purity, optically active monoterpenoid alcohol. This compound is valued for its specific stereochemistry, making it a crucial chiral building block and flavor/fragrance intermediate in advanced synthesis. It is primarily sought after by research institutions and manufacturers in the pharmaceutical, agrochemical, and specialty fragrance industries where enantiomeric purity is critical for product performance and regulatory approval.

Application

• Chiral Intermediate in Pharmaceutical Synthesis: Used in the research and development of active pharmaceutical ingredients (APIs) requiring specific stereocenters.
• Agrochemical Intermediate: Serves as a precursor in the synthesis of chiral pesticides and herbicides, where the biological activity is often enantiomer-specific.
• Fragrance and Flavor Ingredient: Employed as a component in high-end perfumery and flavor compositions due to its minty, woody olfactory characteristics.
• Organic Synthesis Reagent: Acts as a versatile starting material or resolving agent in asymmetric synthesis and methodological studies.
• Reference Standard: Used as an analytical standard in chromatography (GC, HPLC) for quality control and method development in related industries.
