Manufacturing Quality Control of 1-(2-Hydroxyethyl)piperazine
| Test Item | Common Testing Method | Method Description |
|---|---|---|
| Appearance | Visual Inspection | Observe the color and state of the sample under natural light or a standard light source to determine if it is a colorless to slightly yellow transparent liquid, free from turbidity, sediment, or foreign matter. |
| Identification | Infrared Spectroscopy (FT-IR) | Compare the sample with a reference spectrum to confirm the characteristic functional groups (e.g., O-H, C-N, C-O) absorption peaks for qualitative identification. |
| Content Determination | Acid-Base Titration / High-Performance Liquid Chromatography (HPLC) | - Acid-Base Titration: Utilize the basic property of HEP and titrate with a standard acid solution to calculate the main component content. - HPLC Method: Use a C18 column and UV detector (e.g., 210 nm), quantifying by retention time and peak area. This method provides high accuracy and is suitable for complex mixtures. |
| pH Value | pH Meter Measurement | Measure the pH of a specified concentration HEP aqueous solution (e.g., 1% w/v) at room temperature using a calibrated pH meter to control its aqueous acidity or alkalinity. |
| Moisture | Karl Fischer Titration | Determine the water content in the sample using the reaction between iodine and sulfur dioxide in the presence of pyridine and methanol, which reacts quantitatively with water. It is suitable for trace water detection. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | Determine the content of heavy metals such as lead, cadmium, mercury, and arsenic after sample digestion to ensure compliance with pharmacopoeia or industry safety limits. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Use gradient or isocratic elution to separate the main peak and impurity peaks, calculating the content of each impurity by relative retention time and peak area to control purity. |
| Residual Solvents | Gas Chromatography (GC) | Use headspace injection or direct injection to detect residual organic solvents (e.g., ethanol, dichloromethane, toluene) from the production process, complying with ICH limit requirements. |
| Ignition Residue | Ignition Residue Determination | Incinerate the sample at high temperature (500–600°C) until constant weight, then weigh the residue to assess the total inorganic impurity content. |
| Microbial Limit | Microbial Limit Test (Pharmacopoeia Method) | Perform aerobic bacterial count, mold, and yeast count, as well as controlled bacteria (e.g., Escherichia coli) testing according to the Chinese Pharmacopoeia or USP to ensure microbial compliance. |
