| Biochemical Research | Enzyme stabilizer and reducing agent | Employed in laboratory experiments to maintain protein thiol group activity and prevent oxidative inactivation |
Manufacturing Quality Control of Cysteamine bitartrate
| Test Item | Common Test Method | Method Overview |
|---|---|---|
| Identification | Infrared Spectrophotometry (IR) | Confirm molecular structural consistency by comparing the infrared absorption spectrum of the sample with that of a reference standard. |
| Thin-Layer Chromatography (TLC) | Separate sample components on a thin-layer plate and perform qualitative identification by comparing Rf values and spot colors with those of a reference substance. | |
| Assay | High-Performance Liquid Chromatography (HPLC) | Quantitative analysis of the active ingredient using a reversed-phase column and UV detector; calculate content based on peak area using an external standard method. |
| Non-aqueous Titration | Titration with perchloric acid in a non-aqueous solvent, using potentiometric or indicator detection to determine the endpoint and calculate the content. | |
| Related Substances / Impurity Testing | HPLC Method (Related Substances) | Impurities are separated using gradient or isocratic elution; impurity levels are assessed by calculating the percentage of individual peak areas relative to the total area based on specified thresholds. |
| pH Value | pH Meter Method | Prepare a solution of specified concentration and directly measure its pH value using a calibrated pH meter. |
| Loss on Drying | Drying to Constant Weight (105°C) | Dry the sample at 105°C until constant weight is achieved; calculate the percentage weight loss to assess moisture and volatile content. |
| Sulfated Ash | High-Temperature Ashing | The sample is charred and then incinerated in a furnace at 600–800°C; the residue (inorganic matter) is weighed to evaluate levels of inorganic impurities. |
| Heavy Metals | Thioacetamide Method (Chinese Pharmacopoeia) | In weakly acidic conditions, react with thioacetamide to produce coloration; compare visually with a standard lead solution to control total heavy metal content. |
| Water Content | Karl Fischer Titration (Volumetric) | Quantitative reaction of iodine with sulfur dioxide in a pyridine/methanol system with water; water content is determined by titration. |
| Specific Optical Rotation | Polarimetry | Prepare a solution of defined concentration and measure optical rotation at a specified wavelength (typically 589 nm), then calculate the specific optical rotation. |
| Solution Clarity and Color | Visual Comparison (Colorimetry/Turbidimetry) | Compare with standard turbidity or color solutions to evaluate whether solution appearance meets quality requirements. |
| Bacterial Endotoxins | Limulus Amebocyte Lysate Test (LAL Method) | Utilize the clotting reaction between horseshoe crab blood cell extract and endotoxins; detect endotoxin levels via gel-clot or kinetic turbidimetric methods. |
| Microbial Limits | Plate Count Method / Membrane Filtration | Inoculate culture media according to pharmacopoeia guidelines, incubate, and count total aerobic bacteria, molds, and yeasts to control microbial contamination. |
