Description

(S)-4-Dodecanolide Standard For GC is a high-purity chiral chemical reference standard, specifically the (S)-enantiomer of 4-dodecanolide. This compound is essential for accurate analytical calibration and method validation in gas chromatography (GC) and related techniques. It is primarily used by analytical laboratories, quality control departments, and research institutions in the pharmaceutical, fragrance, flavor, and fine chemical industries to ensure precise identification and quantification of lactone compounds.

Application

• Primary Standard for Gas Chromatography (GC): Used for calibrating instruments, validating analytical methods, and ensuring accurate quantitative and qualitative analysis.
• Chiral Reference Material: Serves as a definitive standard for the identification and purity assessment of the (S)-enantiomer in chiral synthesis and separation studies.
• Fragrance and Flavor Analysis: Critical for the quality control of flavoring agents and perfumery ingredients where specific lactone enantiomers define sensory profiles.
• Pharmaceutical Research: Used in the development and testing of chiral active pharmaceutical ingredients (APIs) and in metabolic studies.
• Method Development and Validation: Supports the establishment of regulatory-compliant analytical procedures in compliance with ICH, FDA, and other guidelines.
• Teaching and Research: Employed in academic and industrial R&D settings for studying lactone chemistry, stereochemistry, and analytical techniques.
