Industrial Applications of DL-2-(2-Chlorophenyl)glycine
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Key chiral intermediate for the synthesis of the antibiotic levofloxacin | L-isomer obtained via chiral resolution or asymmetric synthesis, then used in cyclization and fluorination steps to construct the quinolone core |
| Agrochemical Intermediates | Structural building block for novel herbicides and fungicides | Chlorinated aryl glycine derivative employed in amidation and cyclization reactions to assemble the active molecular scaffold |
| Organic Synthesis | Precursor for chiral ligands and functional materials | Specific functional groups introduced via esterification, reduction, or coupling reactions for catalyst design or polymer monomer synthesis |
Manufacturing Quality Control of DL-2-(2-Chlorophenyl)glycine
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Content Assay | High-Performance Liquid Chromatography (HPLC) | Utilizes a reversed-phase C18 column with a mobile phase such as phosphate buffer-methanol, detected by a UV detector (e.g., 210 nm or 254 nm). Quantification is performed using external or internal standard methods. Suitable for determining purity and active ingredient content. |
| Chiral Purity (Enantiomeric Ratio) | Chiral High-Performance Liquid Chromatography (Chiral HPLC) | Employs chiral stationary phase columns (e.g., Chiralpak AD-H, AS-H, etc.) under normal-phase or polar organic conditions to separate D- and L-isomers, evaluating enantiomeric excess (ee value) to control optical purity. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Uses gradient elution to enhance separation capability, detecting possible synthetic intermediates, by-products, or degradation products in the active pharmaceutical ingredient. Impurity peak areas are calculated and controlled within specified limits. |
| Melting Point | Capillary Melting Point Determination | Sample is loaded into a capillary tube and heated gradually in a melting point apparatus; the initial and complete melting temperatures are observed. DL-o-chlorophenylglycine typically exhibits a specific melting range, used for preliminary identification and purity assessment. |
| Water Content | Karl Fischer Titration | Determines water content in samples using a Karl Fischer titrator, available in volumetric or coulometric modes, suitable for controlling moisture loss and process stability. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Drying Method | Sample is dried at a specified temperature (e.g., 105°C) until constant weight is achieved; percentage weight loss is calculated to reflect crystalline water or residual solvents. |
| Residue on Ignition (Sulfated Ash) | Gravimetric Method | Sample is treated with sulfuric acid and then incinerated at high temperature; the mass of residual inorganic material is weighed to control inorganic impurities. |
| Heavy Metals | Sulfide Colorimetric Method (Chinese Pharmacopoeia Method) | In acidic conditions, reacts with hydrogen sulfide or thioacetamide to form colored precipitates; colorimetric determination of total heavy metals such as lead. |
| Solution Clarity and Color | Visual Color Comparison / Turbidity Method | Sample is dissolved in a specified solvent (e.g., water or ethanol) and compared visually with standard color or turbidity reference solutions to assess solution appearance quality. |
| Structure Confirmation | Infrared Spectroscopy (IR), Nuclear Magnetic Resonance (NMR), Mass Spectrometry (MS) | IR identifies functional groups; ¹H-NMR and ¹³C-NMR confirm molecular structure; MS provides molecular ion peaks and fragmentation patterns, used collectively for structural confirmation. |
