| Industry | Application | Process |
|---|---|---|
| Chemical Industry | Fragrance Synthesis | Used as an intermediate in the synthesis of floral- or fruity-odor compounds |
| Personal Care Industry | Fragrance Ingredient | Formulated into fragrance compositions for perfumes, skincare products, and similar applications |
| Food Industry | Food Flavoring | Employed as a food additive to impart specific aromatic characteristics to food products |
| Test Item | Common Test Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Place the sample in a clean, colorless glass container and visually examine its color, physical state, and clarity (transparent or not) under natural light or standard illumination. Assess for the presence of impurities, turbidity, or precipitates. |
| Color Intensity | Platinum-Cobalt Colorimetric Method (GB/T 3143 or ASTM D1209) | Compare the sample solution's color against standard platinum-cobalt solutions using either a spectrophotometer or visual comparison to determine the color value (in Hazen or APHA units), assessing the degree of oxidation or impurity. |
| Assay/Purity | Gas Chromatography (GC) | Quantitative analysis of the main component using a capillary column (e.g., HP-5, DB-WAX) and FID detector, with internal or external standard method to calculate the compound's purity. This method offers high sensitivity and good reproducibility. |
| Impurity Analysis | Gas Chromatography-Mass Spectrometry (GC-MS) | Combines the separation capability of gas chromatography with the identification power of mass spectrometry to detect and identify organic impurities (e.g., isomers, degradation products, by-products), supporting quality traceability and safety evaluation. |
| Moisture Content | Karl Fischer Titration | Measures trace moisture content based on the quantitative reaction between water and Karl Fischer reagent, using coulometric or volumetric titration. Suitable for precise control of low moisture levels. |
| Refractive Index | Refractometry (according to GB/T 6488 or ISO 759) | Measure the refractive index (n20D) of the sample using an Abbe refractometer at a specified temperature (usually 20°C or 25°C). Used as a physical constant for identification and preliminary purity screening. |
| Density | Pycnometer Method or Digital Density Meter (ISO 1675) | Determine the mass per unit volume under constant temperature using a calibrated pycnometer or oscillating U-tube digital densitometer, for verification of physical properties. |
| Odor Evaluation | Sensory Analysis (Olfactory Assessment) | Trained fragrance evaluators assess the aroma profile, intensity, and presence of off-odors in a standardized environment to determine compliance with desired fragrance characteristics. |
| Infrared Spectroscopy (IR) | Fourier Transform Infrared Spectroscopy (FT-IR) | Obtain an infrared absorption spectrum by scanning the sample and compare it with reference spectra to confirm functional groups in the molecular structure (e.g., carbonyl C=O, C=C double bonds). |
