| Cosmetics | Synthetic raw material | Used in the preparation of cosmetic ingredients with specific functionalities |
Manufacturing Quality Control of 1,2,3,4-TETRAHYDROISOQUINOLINE
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Content Assay | High-Performance Liquid Chromatography (HPLC) | Utilizes a reversed-phase C18 column with a UV detector (typically at 254 nm or 280 nm wavelength) for quantification of target compounds using external standard or internal standard methods. The mobile phase commonly consists of methanol-water or acetonitrile-water systems, with buffer salts added to adjust pH for improved peak shape. |
| Purity Analysis | Gas Chromatography (GC) | Applicable to samples with good volatility. Uses capillary columns (e.g., DB-5) with an FID detector; purity and impurity levels are assessed via normalization or external standard methods. Attention must be paid to the thermal stability of the compound to avoid decomposition. |
| Structure Confirmation | Nuclear Magnetic Resonance Spectroscopy (NMR) | Confirms molecular structure using ¹H-NMR and ¹³C-NMR, identifying characteristic proton signals (e.g., aromatic rings, methylene groups) to verify consistency with the target structure. |
| Impurity Analysis | Liquid Chromatography-Mass Spectrometry (LC-MS) | Combines the separation capability of HPLC with the qualitative power of mass spectrometry to identify potential residual intermediates, by-products, or degradation impurities from synthesis, providing molecular ion peaks and fragmentation patterns. |
| Residual Solvent Detection | Gas Chromatography (GC) | According to pharmacopoeial requirements (e.g., Chinese Pharmacopoeia, USP), headspace-GC is used to detect residual organic solvents used in manufacturing (e.g., methanol, ethanol, dichloromethane). |
| Water Content | Karl Fischer Titration | Accurately determines water content in samples, available in volumetric and coulometric forms; suitable for quality control of moisture-sensitive organic compounds. |
| Melting Point Determination | Melting Point Apparatus | Measures the melting temperature range of solid samples using a melting point instrument, serving as a physical property reference to assist in assessing compound purity and consistency. |
