Manufacturing Quality Control of 2,2-BIS(4-HYDROXY-3,5-DIMETHYLPHENYL)PROPANE
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Purity / Assay | High-Performance Liquid Chromatography (HPLC) | Uses a reversed-phase C18 column and a UV detector (typically at 220–280 nm wavelength). The purity of TMBPA is calculated based on the main peak area using external standard or area normalization methods. |
| Related Substances / Impurities | High-Performance Liquid Chromatography (HPLC) | Separates and quantifies potential process-related impurities (e.g., incompletely methylated intermediates, isomers) under the same conditions as purity testing. Impurity limits are set and controlled accordingly. |
| Melting Point | Melting Point Determination (Capillary Method or Digital Melting Point Apparatus) | The sample is packed into a capillary tube and heated gradually in a controlled temperature device. The initial and final melting temperatures are observed to assess crystalline purity and batch consistency. |
| Moisture Content | Karl Fischer Titration | Measures moisture content by the quantitative reaction between KF reagent and water in the sample, using either coulometric or volumetric titration. Suitable for trace moisture control. |
| Residual Solvents | Gas Chromatography (GC) | Uses headspace or direct injection with an FID detector to determine residual levels of organic solvents (e.g., toluene, acetone) used in synthesis, according to pharmacopeial or process requirements. |
| Heavy Metals | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) or Atomic Absorption Spectroscopy (AAS) | After acid digestion of the sample, ICP-MS or AAS is used to measure trace levels of heavy metal elements such as lead, cadmium, mercury, and arsenic to ensure compliance with safety limits. |
| Appearance and Color | Visual Comparison or Colorimeter | Sample color (typically white to off-white crystalline powder) is visually inspected under standard lighting. A colorimeter may be used when necessary to quantify color values such as Lab*. |
| Infrared Spectroscopic Identification | Fourier Transform Infrared Spectroscopy (FT-IR) | Records the infrared absorption spectrum of the sample and compares characteristic peaks (e.g., phenolic hydroxyl, aromatic ring, methyl groups) with reference spectra for structural confirmation and authenticity verification. |
