| Environmental Protection | Treatment of heavy metal–containing wastewater | Chelation of heavy metal ions to form separable compounds |
| Chemical Manufacturing | Synthesis of other chelating agents or ligands | Introduction of specific functional groups via chemical reaction |
| Pharmaceuticals | Intermediate in drug synthesis | Participation in organic synthesis reactions to construct the target molecular scaffold |
Manufacturing Quality Control of Sodium hydrogen ferric DTPA
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Identification Test | Infrared Spectroscopy (IR) | By measuring the infrared absorption spectrum of the sample and comparing it with the standard spectrum, the presence of characteristic functional groups (such as carboxylate, amine groups, etc.) can be confirmed to verify the compound's structure. |
| Elemental Analysis (EA) | Determine the content of elements such as C, H, N, Fe, and Na in the sample, and compare it with the theoretical values to assist in confirming the molecular composition. | |
| Content Determination | Complexometric Titration (EDTA Back Titration) | Excess standard EDTA solution is used to complex with Fe³⁺ in the sample, followed by back-titration with Zn²⁺ or Bi³⁺ standard solution to determine the iron content, indirectly calculating the content of the complex. |
| Atomic Absorption Spectroscopy (AAS) or Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Directly determine the content of iron (Fe) and sodium (Na) in the sample, and calculate the purity of the complex based on the theoretical ratio. | |
| pH Value | pH Meter Measurement | Prepare a solution of the sample at a specified concentration (e.g., 1% w/v), and measure its pH value using a calibrated pH meter to assess the acidity or alkalinity of the product, which should meet the standard (usually between 6.0–8.0). |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Atmospheric Drying Method | Dry the sample at 105°C until constant weight is achieved, and measure the percentage of mass loss to control moisture and volatile impurities. |
| Heavy Metal Limit | Sulfanilamide Colorimetric Method or ICP-MS | Determine the total amount of heavy metals such as lead, arsenic, cadmium, and mercury using the general method of pharmacopoeia (e.g., Chinese Pharmacopoeia General Chapter 0821) or high-sensitivity ICP-MS, ensuring compliance with safety limits (typically ≤20 ppm). |
| Free Iron Ions | Spectrophotometry (Thiocyanate Method) | In acidic conditions, free Fe³⁺ reacts with potassium thiocyanate to form a red complex, and the absorbance is measured at 480 nm to evaluate the residual amount of uncomplexed iron. |
| Chloride/Sulfate Impurities | Ion Chromatography (IC) or Turbidity Method | Quantify anions such as Cl⁻ and SO₄²⁻ using ion chromatography according to pharmacopoeia methods, or use nitric silver/chloride barium turbidity for qualitative or semi-quantitative control. |
| Solution Clarity and Color | Visual Colorimetry or UV-Vis Spectrophotometry | Prepare a solution of a certain concentration, and compare it with standard turbidity/color solutions to determine the presence of insoluble substances or colored impurities. |
