Manufacturing Quality Control of 4-Bromophenylacetic acid
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color and condition of the sample (usually white to off-white crystalline powder), checking for any foreign matter or discoloration. |
| Purity/Content | High-Performance Liquid Chromatography (HPLC) | Using a C18 chromatographic column and UV detector (e.g., 220 nm or 254 nm), quantification is performed using external standard or area normalization method. |
| Melting Point | Capillary Melting Point Determination | Determined using a digital melting point apparatus; the typical melting point range for bromobenzoic acid is approximately 118–122°C, used to assess purity. |
| Loss on Drying | Drying Method (105°C to constant weight) | Weigh the sample in a pre-weighed weighing bottle, dry at 105°C until constant weight is achieved, and calculate the percentage loss to control moisture content. |
| Residue on Ignition | High-Temperature Ashing Method | After high-temperature incineration (typically 700–800°C), weigh the residual mass to evaluate inorganic impurities. |
| Heavy Metals | Heavy Metal Test Method from the Chinese Pharmacopoeia | Use thiocyanate method or atomic absorption spectroscopy (AAS) to control limits of heavy metals such as lead, arsenic, and mercury. |
| Related Substances | HPLC Gradient Elution Method | Separate main component and impurity peaks by optimizing the mobile phase gradient to detect synthetic by-products or degradation products. |
| pH Value (Solution) | pH Meter Measurement Method | Prepare a certain concentration aqueous solution (e.g., 1%), measure with a calibrated pH meter to assess acidity and ensure it meets expectations. |
| Residual Solvents | Gas Chromatography (GC-FID/HS-GC) | Determine residual organic solvents (e.g., methanol, ethyl acetate) using headspace sampling or direct injection. |
| Halogen Content (Bromine) | Oxygen Flask Combustion-Titration Method or ICP-MS | Determine bromine content through titration after oxygen flask combustion or via inductively coupled plasma mass spectrometry (ICP-MS) to verify structural correctness. |
