Manufacturing Quality Control of (R)-(-)-Methyl mandelate
| 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. |
| Optical Rotation | [alpha]D Measurement using Polarimetry | Measures the angle of rotation of plane-polarized light caused by chiral molecules in solution at specified temperature and concentration. |
| Water Content | Karl Fischer Titration (Coulometric or Volumetric) | Electrochemical titration where iodine reacts stoichiometrically with water; endpoint detected amperometrically or potentiometrically. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatile solvents are equilibrated in headspace vial, then injected and separated on GC column for quantitative analysis. |
| Heavy Metals | ICP-OES (Inductively Coupled Plasma Optical Emission Spectrometry) | Atomization and excitation of metal ions in high-temperature plasma; quantification via element-specific emission intensities. |
| Chloride Impurity | Ion Chromatography (IC) with Conductivity Detection | Separation of anions on ion-exchange column followed by conductivity-based quantification relative to chloride standard. |
| Acid Value | Acid-Base Titration with NaOH standard solution | Neutralization of free carboxylic acid groups using standardized sodium hydroxide; endpoint detected potentiometrically or with phenolphthalein. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Sample is ignited at 700-800 C to volatilize organic matter; residue weight represents inorganic ash content. |
| Appearance | Visual Inspection against Standard White Background | Assessment of physical state, color, and clarity in a transparent container under controlled lighting conditions. |
| Melting Point | Capillary Melting Point Determination | Thermal transition observed as solid-to-liquid phase change using calibrated digital melting point apparatus. |
| Related Substances | High Performance Liquid Chromatography (HPLC) with UV detection | Separation of structurally similar compounds on reversed-phase column; detection and quantification at characteristic UV wavelength. |
| Specific Gravity | Digital Density Meter Measurement | Determination of mass per unit volume at 20 C using oscillating U-tube principle with temperature-controlled sample. |
