Description

(S)-4-Nonanolide Standard For Gc is a high-purity analytical reference standard of the enantiomerically pure lactone compound. This standard is essential for ensuring accurate qualitative and quantitative analysis in gas chromatography (GC) and other analytical methods. It is primarily used by analytical laboratories, quality control departments, and research institutions in the pharmaceutical, flavor & fragrance, and fine chemical industries for method development, validation, and routine testing.

Application

• Primary Standard for Gas Chromatography (GC): Used for instrument calibration, peak identification, and quantification in GC and GC-MS analyses.
• Chiral Reference Material: Serves as a definitive standard for the analysis and quality control of enantiomerically pure (S)-4-Nonanolide in flavor and fragrance formulations.
• Pharmaceutical Impurity Profiling: Employed as a reference compound in the identification and quantification of related substances or degradation products in active pharmaceutical ingredients (APIs).
• Flavor & Fragrance R&D and QC: Critical for authenticating and standardizing the chiral signature of γ-nonalactone, a key compound with creamy, coconut-like aroma notes.
• Method Development & Validation: Provides a known, pure substance for developing and validating new analytical procedures in compliance with ICH and pharmacopeial guidelines.
• Academic and Industrial Research: Used as a building block or reference in synthetic organic chemistry and stereochemical studies.
