Description

(1S)-(+)-Neomenthyl Acetate CAS NO 2552-91-2 is a high-purity, chiral ester derivative of neomenthol, valued for its distinct olfactory profile and stereochemical purity. This compound is essential for applications requiring a specific enantiomeric form to achieve desired sensory or chemical outcomes. It is primarily sought by manufacturers in the fragrance, flavor, and fine chemical synthesis industries for its role as a key chiral intermediate and aroma chemical.

Application

• Fragrance Formulation: Used as a chiral building block and modifier in high-end perfumes, colognes, and personal care products to impart fresh, minty, or woody notes with specific stereochemical characteristics.
• Flavor Enhancement: Employed as a flavoring agent in food and beverage products, contributing to complex mint or herbal flavor profiles where enantiopurity is critical for taste quality.
• Pharmaceutical Intermediates: Serves as a valuable chiral synthon in the asymmetric synthesis of active pharmaceutical ingredients (APIs) and other bioactive molecules.
• Chemical Research & Development: Utilized as a standard or reagent in organic synthesis, catalysis studies, and stereochemistry research within academic and industrial R&D laboratories.
• Agrochemical Synthesis: Acts as a precursor in the production of certain chiral agrochemicals, where the specific stereoisomer can influence biological activity.

Quality Control

Our (1S)-(+)-Neomenthyl Acetate is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity assessment by GC or HPLC, to ensure it meets exacting specifications for enantiomeric excess and chemical purity. A Certificate of Analysis (COA) detailing identity, assay, impurity profile, and physical properties is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and open flame. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and maintain product integrity. Recommended storage temperature is 2-8°C for long-term stability.
