Manufacturing Quality Control of 2,3-Pyridinedicarboxylic acid
| 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 characteristic functional groups and structure of 2,3-pyridinedicarboxylic acid can be confirmed. |
| Proton Nuclear Magnetic Resonance (¹H NMR) | Using nuclear magnetic resonance technology to analyze the chemical shift and coupling constants of hydrogen atoms in the molecule, verifying the compound's structure. | |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Using a reversed-phase C18 column, with phosphate buffer solution-methanol or acetonitrile as the mobile phase, and a UV detector (e.g., 254 nm) for quantitative analysis of the main component content. |
| Acid-Base Titration | Utilizing its properties as a diprotic carboxylic acid, titrating with a standard NaOH solution, determining the endpoint by phenolphthalein or potentiometry, and calculating the content. | |
| Related Substances / Impurity Testing | High-Performance Liquid Chromatography (HPLC) | Using a gradient elution program to separate and detect possible process impurities or degradation products. Quantification is typically performed using area normalization or the correction factor method with the main component as reference. |
| Drying Loss | Thermogravimetric Analysis (TGA) or Constant Weight Method | Drying the sample at a specified temperature (e.g., 105°C) until constant weight is achieved, measuring the mass loss to evaluate moisture and volatile substance content. |
| Ignited Residue | High-Temperature Ashing | After high-temperature ignition (usually 700–800°C), the mass of the residual inorganic material is measured to control the limit of inorganic impurities. |
| pH Value | pH Meter Measurement | Preparing an aqueous solution of a certain concentration (e.g., 1% w/v), and measuring its pH value using a calibrated pH meter. |
| Melting Point | Melting Point Determination | Using a capillary tube method or digital melting point apparatus to determine the melting temperature range, serving as a supplementary indicator for purity and identity. |
