Industrial Applications of 2-Phenylbutyric acid
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Synthetic intermediate for non-steroidal anti-inflammatory drugs (e.g., ibuprofen) | Organic synthesis, esterification |
| Fine fragrances | Used in fruit-flavored fragrance formulations to impart sweet and fruity base notes | Fragrance compounding, solvent dilution |
| Organic synthesis | Chiral building block for constructing complex molecular architectures | Catalytic asymmetric synthesis, coupling reactions |
| Personal care & cosmetics | Slow-release fragrance ingredient to extend scent longevity in skincare products and perfumes | Microencapsulation, emulsification |
| Food additives | Used at trace levels in food flavorings (subject to regulatory limits) | Solvent extraction, distillation purification |
Manufacturing Quality Control of 2-Phenylbutyric acid
| Test Item | Common Testing Method | Method Description |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color and state (e.g., white to off-white crystals or powder) to determine if it meets the standard description. |
| Purity/Content | High-Performance Liquid Chromatography (HPLC) | Use a C18 column and a UV detector (typically 210–254 nm). Quantify the main component using external standard method or area normalization. |
| Related Substances | HPLC (Gradient Elution) | Separate impurities using a gradient elution program. Identify known impurities by comparison with reference standards or relative retention time, and control total impurity content and individual impurity limits quantitatively. |
| Water Content | Karl Fischer Titration | Determine trace water content in the sample using electrochemical titration. Suitable for organic acid compounds. |
| Residual Solvents | Gas Chromatography (GC) | Use headspace injection or direct injection with a capillary column for separation. Use FID detector to quantify residual organic solvents (e.g., methanol, ethanol, ethyl acetate, etc.). |
| Melting Point | Capsule Melting Point Determination | Determine the temperature range from initial melting to complete melting, used for identification and preliminary purity assessment. |
| pH Value | pH Meter Method | Determine acidity or alkalinity by measuring a solution of specified concentration (e.g., 1%) using a calibrated pH meter, reflecting the free acid state. |
| Heavy Metals | Heavy Metal Test according to Chinese Pharmacopoeia (Thioacetamide Method) | In weakly acidic conditions, react with thioacetamide to produce a color. Compare with standard lead solution to control total heavy metal content (as Pb). |
| Ignition Residue | Gravimetric Method | Weigh the residue after incinerating the sample at high temperature (600–800°C) to assess the total inorganic impurity content. |
| Specific Rotation (if applicable) | Polarimeter Method | If the compound is chiral and specified in the standard, measure the optical rotation of a solution of specific concentration under sodium D light to control optical purity. |
