| Industry | Application | Process |
|---|---|---|
| Fine Fragrances & Flavorings | Used as a musk fragrance ingredient to impart long-lasting animalic musk notes in premium perfumes, cosmetics, and household products | Synthesized via organic synthesis using cycloheptadecenone as the core structure, followed by selective oxidation and isomerization; (Z)-configuration is typically controlled using catalytic oxidation or biocatalytic (enzymatic) methods |
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Identification | Infrared Spectroscopy (IR) | Confirms molecular structure by identifying characteristic functional group absorption peaks (e.g., carbonyl C=O at ~1700 cm⁻¹, C=C at ~1650 cm⁻¹). |
| Proton Nuclear Magnetic Resonance (¹H NMR) | Analyzes chemical shifts, coupling constants, and integration areas of hydrogen atoms to verify the (Z)-configuration and cyclic structure. | |
| Gas Chromatography-Mass Spectrometry (GC-MS) | Performs qualitative identification based on retention time and mass spectral fragments (e.g., m/z 266 [M]⁺). | |
| Assay | Gas Chromatography (GC) | Quantifies the main component using internal or external standard methods based on peak area; suitable for samples with good volatility. |
| High-Performance Liquid Chromatography (HPLC) | Employs a C18 reversed-phase column with UV detection (e.g., 210–230 nm); suitable for thermally unstable or non-volatile samples. | |
| Related Substances (Impurities) Check | GC or HPLC (depending on sample properties) | Uses gradient elution or programmed temperature rise to separate and quantify process-related impurities and degradation products; typically reported by area normalization. |
| Water Content | Karl Fischer Titration | A highly specific and accurate method for determining trace moisture; a critical parameter affecting stability. |
| Residual Solvents | Headspace-Gas Chromatography (HS-GC) | Detects residual organic solvents (e.g., methanol, ethanol, dichloromethane) from manufacturing processes, in compliance with ICH Q3C guidelines. |
| Melting Point / Boiling Point | Melting point apparatus or boiling point determination device | Assists in purity identification; pure substances exhibit a defined melting or boiling range. |
| Optical Purity (if applicable) | Chiral HPLC or Optical Rotation Measurement | For compounds with chiral centers, enantiomeric purity must be assessed; although this compound has no chiral center, (Z)/(E) isomers require monitoring. |
| (Z)/(E) Isomer Ratio | GC or HPLC (using polar stationary phase) | Quantifies (Z)-isomer purity by exploiting differences in retention time between cis-trans isomers on the chromatographic column, ensuring consistency of aroma characteristics. |
