Manufacturing Quality Control of Diethyl 3,5-di-tert-butyl-4-hydroxybenzyl phosphate
| Detection Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Place the sample against a white background and visually inspect its color and physical state. The qualified product should appear as a white to off-white powder or granules, free of visible impurities. |
| Melting Point | Capillary Melting Point Determination | Use a melting point apparatus to determine the melting temperature range. The typical melting point of Irganox 1222 is approximately 108–112°C. |
| Content (Purity) | High-Performance Liquid Chromatography (HPLC) | Utilize a reversed-phase C18 column with UV detection (e.g., at 280 nm), and determine the main component content via external standard or internal standard method to assess purity. |
| Volatile Matter (Moisture + Volatiles) | Thermogravimetric Analysis (TGA) or Oven Loss Method | Heat the sample at a specified temperature (e.g., 105°C) for a set duration (e.g., 2 h), then measure the mass loss to determine the content of volatile components. |
| Ash Content | Ignition Residue Test (Muffle Furnace Method) | Incinerate the sample at high temperature (e.g., 800±25°C) until constant weight is achieved; weigh the residual inorganic matter and calculate the ash percentage. |
| Hydroxyl Value | Titration Method (Acetylation Method) | React the sample with acetic anhydride, hydrolyze the resulting ester, and titrate the liberated acetic acid with standardized base to calculate hydroxyl group content, used to verify structural integrity. |
| Infrared Spectroscopy (IR) | Fourier Transform Infrared Spectroscopy (FT-IR) | Perform pellet or ATR testing on the sample to obtain characteristic absorption peaks, which are compared with reference spectra to confirm molecular structure consistency. |
| Heavy Metal Content | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, determine the levels of heavy metals such as lead, cadmium, and mercury to ensure compliance with environmental and safety standards (e.g., RoHS). |
| Microbial Limits | Microbial Limit Test | Conduct tests for total aerobic bacteria, mold, and yeast counts according to pharmacopeial or relevant standards, applicable to pharmaceutical or food-grade products. |
