Description

(S)-4-Undecanolide Standard For GC is a high-purity chiral reference standard of a γ-lactone, specifically the (S)-enantiomer of 4-undecanolide. This compound is essential for the accurate calibration, identification, and quantification of flavor and fragrance components in analytical chemistry. It is primarily required by analytical laboratories, quality control departments, and research institutions in the flavor & fragrance, food & beverage, and pharmaceutical industries to ensure method validation and regulatory compliance.

Application

• Gas Chromatography (GC) Reference Standard: Primary use for instrument calibration, method development, and system suitability testing.
• Flavor and Fragrance Analysis: Used as an analytical standard for identifying and quantifying γ-undecalactone and related lactones in complex matrices.
• Chiral Separation Studies: Serves as a pure enantiomeric standard for developing and validating chiral chromatography methods.
• Quality Control (QC) in Manufacturing: Ensures the purity and enantiomeric excess of lactone-based ingredients in final products.
• Research and Development: Acts as a building block or reference material in synthetic organic chemistry and sensory science research.
• Regulatory Compliance and Testing: Supports testing for compliance with food safety (FDA, EFSA) and fragrance industry (IFRA) standards.
