Description

(R)-4-Undecanolide Standard For GC is a high-purity chiral reference standard, specifically the (R)-enantiomer of γ-undecalactone. This compound is essential for the accurate calibration, method development, and quality control of analytical instruments, particularly Gas Chromatography (GC) systems. It is a critical material for analytical laboratories, flavor and fragrance manufacturers, and research institutions requiring precise enantiomeric identification and quantification.

Application

• Primary Standard for Gas Chromatography (GC): Used for instrument calibration, peak identification, and quantitative analysis in GC and GC-MS methods.
• Chiral Reference Material: Serves as an authentic standard for the analysis and separation of γ-undecalactone enantiomers in complex matrices.
• Flavor and Fragrance Analysis: Critical for quality control and authenticity verification in the flavor and fragrance industry, where γ-undecalactone is a key aroma compound (peach, coconut).
• Pharmaceutical Research: Used in chiral synthesis and analytical method development for pharmaceutical intermediates and active ingredients.
• Food and Beverage Testing: Employed in laboratories to quantify natural and synthetic flavoring agents in food products and beverages.
• Academic and Industrial R&D: Supports research in organic chemistry, stereochemistry, and the development of new analytical methodologies.
