Industrial Applications of IPTG
| Industry | Application | Process |
|---|---|---|
| Biotechnology | As an IPTG inducer for genetic regulation in recombinant protein expression systems (e.g., E. coli expression systems) | Used in molecular biology experiments |
| Pharmaceuticals | For manufacturing recombinant proteins, vaccines, and biopharmaceuticals | Applied in fermentation and downstream purification processes |
| Research | For studying gene expression regulation mechanisms and protein function | Used in laboratory-scale induction and detection |
Manufacturing Quality Control of IPTG
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Assessed by naked-eye observation of color, physical state (e.g., white or off-white crystalline powder), and presence of foreign matter to determine compliance with specified requirements. |
| Identification Test | Infrared Spectroscopy (IR) Nuclear Magnetic Resonance Hydrogen Spectroscopy (¹H NMR) |
IR: Measures the infrared absorption spectrum of the sample and compares it with a reference standard spectrum to confirm characteristic functional groups; ¹H NMR: Confirms molecular structure through chemical shift and coupling constant analysis, verifying that the compound is isopropyl-β-D-thiogalactopyranoside. |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Uses a reversed-phase C18 column with an appropriate mobile phase (e.g., acetonitrile-water or methanol-water system) for gradient or isocratic elution. UV detection (typically at 200–220 nm) is employed, and the main component content is calculated using external standard method or area normalization. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Same or optimized separation conditions as in content determination; used to detect and quantify potential synthetic by-products, degradation products, or other organic impurities. Typically, individual impurities ≤ 0.5%, total impurities ≤ 1.0%. |
| Moisture Content | Karl Fischer Titration | Determines water content via quantitative reaction between Karl Fischer reagent and moisture in the sample, using potentiometric or coulometric titration. Moisture is controlled within specified limits (e.g., ≤ 5.0%). |
| Residual Solvents | Gas Chromatography (GC) | Utilizes headspace or direct injection, separated on a DB-624 or similar polar capillary column, detected by FID. Residual organic solvents (e.g., methanol, ethanol, acetone, dichloromethane) are determined according to ICH Q3C guidelines with established acceptance limits. |
| Sulfated Ash / Residue on Ignition | Gravimetric Method | Sample is ignited at high temperature until constant weight is achieved; the mass of residual inorganic matter is measured to assess total inorganic impurity levels. Typically required to be ≤ 0.1%. |
| Specific Rotation | Polarimeter Method | A solution of defined concentration is prepared and its optical rotation is measured under specified temperature and wavelength (typically sodium D line, 589 nm). Specific rotation is calculated to verify optical purity and configuration (β-D configuration should exhibit a specific range of rotation values). |
| pH Value | pH Meter Method | A solution of specified concentration (e.g., 1% w/v) is prepared and its pH is measured using a calibrated pH meter. The pH is generally expected to be within the range of 5.0–7.0. |
