Manufacturing Quality Control of o-Toluic acid
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color and condition of the sample under natural light or standard light source to determine if it is a white to slightly yellow crystalline powder, and whether there are any impurities or foreign substances. |
| Melting Point | Capillary Melting Point Determination | Determine the melting temperature using a melting point apparatus. The standard melting point of o-methylbenzoic acid is approximately 103–105 °C, used to assess purity. |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Use a reverse-phase C18 chromatographic column with a UV detector (e.g., 254 nm), and determine the main component content via external or internal standard methods. It is highly accurate and suitable for quantitative analysis. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Same as above, use gradient elution to separate possible organic impurities (such as meta-/para-methylbenzoic acid, oxidation products, etc.), calculate the peak area of each impurity, and control the limit. |
| Moisture | Karl Fischer Titration | Determine the moisture content in the sample using Karl Fischer reagent through titration, which can be either volumetric or coulometric method, suitable for precise determination of trace moisture. |
| Dry Loss | Thermogravimetric Method (Dry Loss Determination) | Dry the sample at a specified temperature (e.g., 105 °C) until constant weight, and calculate the volatile matter content based on the mass loss. |
| Residue on Ignition (Sulfate Ash) | Gravimetric Method | Weigh the residue after high-temperature incineration of the sample and treatment with sulfuric acid, used to evaluate the inorganic impurity content. |
| pH Value (Solution) | pH Meter Measurement | Prepare a suspension or ethanol solution of o-methylbenzoic acid at a certain concentration, and measure its acidity or alkalinity using a calibrated pH meter. |
| Infrared Spectroscopy Identification | Fourier Transform Infrared Spectroscopy (FT-IR) | Scan the sample using infrared spectroscopy and compare with standard spectra to confirm characteristic peaks of molecular structure (such as carboxyl group, aromatic ring, methyl group, etc.) for qualitative identification. |
| Heavy Metals | Sulfide Colorimetric Method (Pharmacopoeia Method) | According to the Chinese Pharmacopoeia or relevant standards, perform a sulfide sodium color reaction, and determine the limit of heavy metals such as lead by visual inspection or spectrophotometry. |
