Manufacturing Quality Control of METHYL 3-HYDROXYPROPANOATE
| 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 polar capillary column. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water; endpoint detected amperometrically. |
| Acidity (as HCl) | Acid-Base Titration with NaOH standard solution | Neutralization of acidic impurities (e.g., residual HCl, free acid) using phenolphthalein or potentiometric endpoint detection. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Measurement of non-volatile inorganic residue after controlled high-temperature ashing at 700–800 °C. |
| Heavy Metals (Pb, Cd, Hg, As) | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Multi-element trace metal quantification via ionization in plasma and mass-selective detection with isotopic resolution. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement (430 nm) | Evaluation of yellowness intensity by matching sample absorbance at 430 nm to APHA platinum-cobalt standards. |
| Refractive Index | Refractometry (at 20 °C) | Measurement of light bending angle in the liquid sample relative to air, correlated to molecular composition and purity. |
| Specific Optical Rotation | Polarimetry (at 20 °C, D-line) | Determination of chiral purity by measuring angular rotation of plane-polarized light induced by optically active molecules. |
| Residual Solvents (Methanol, Ethyl Acetate) | Headspace Gas Chromatography (HS-GC) with FID | Quantitative analysis of volatile solvents via equilibrium vapor phase sampling and separation on a DB-624 column. |
| Related Substances (Impurity Profile) | Gas Chromatography–Mass Spectrometry (GC-MS) | Separation and identification/quantification of structurally related impurities (e.g., 3-hydroxypropionic acid, methyl acrylate) using retention time and spectral matching. |
| Density | Oscillating U-tube Densitometry (at 20 °C) | Precise density measurement based on resonant frequency shift of a vibrating U-shaped glass tube filled with sample. |
| Chloride Ion | Ion Chromatography (IC) with Conductivity Detection | Anion separation on an ion-exchange column followed by quantitative conductivity detection of eluted chloride. |
| Peroxide Value | Iodometric Titration | Oxidation of iodide to iodine by organic peroxides in acidic medium, followed by titration of liberated iodine with sodium thiosulfate. |
| Appearance | Visual Inspection (in clear glass container under controlled lighting) | Assessment of clarity and absence of suspended particles or phase separation against specified visual criteria (e.g., “clear, colorless liquid”). |
