Manufacturing Quality Control of 5-Hydroxypentanoic acid methyl ester
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a calibrated column and carrier gas. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based solvent system. |
| Acid Value | Acid-Base Titration with NaOH | Neutralization of free carboxylic acid groups by standardized sodium hydroxide solution using phenolphthalein indicator. |
| Ester Content | Gas Chromatography (GC) with internal standard | Quantification relative to a stable, non-interfering internal standard (e.g., methyl caproate) co-injected with sample. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after controlled high-temperature ashing and cooling in a desiccator. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after acid digestion by measuring absorbance at element-specific wavelengths. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride anions using anion-exchange column and conductivity detection. |
| Refractive Index | Refractometry | Measurement of light bending angle at air-sample interface at specified temperature (20 C) to assess purity and concentration. |
| Specific Gravity | Pycnometry | Determination of density ratio relative to water using a calibrated glass pycnometer at 20 C. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Assessment of yellowness intensity by matching sample color to APHA platinum-cobalt standard solutions or measuring absorbance at 430 nm. |
| Non-Volatile Residue | Evaporation Gravimetry | Weighing residue remaining after gentle evaporation of a known sample mass under controlled temperature and airflow. |
| Related Substances | High-Performance Liquid Chromatography (HPLC) with UV detection | Separation and quantification of structurally similar impurities using reversed-phase C18 column and UV detection at 210 nm. |
