Manufacturing Quality Control of methyl hydrogen heptane-1,7-dioate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 210 nm based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities using gradient HPLC-UV; identification by retention time matching and/or spiked standards. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., methanol, ethyl acetate) via headspace GC with flame ionization detection using calibrated standards. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration where iodine reacts stoichiometrically with water in pyridine-methanol medium. |
| Acid Value | Acid-Base Titration | Measures free carboxylic acid groups by titration with standardized NaOH solution using phenolphthalein or potentiometric endpoint detection. |
| Heavy Metals | ICP-OES | Quantifies elemental impurities (e.g., Pb, Cd, Hg, As) after acid digestion using inductively coupled plasma optical emission spectroscopy. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with conductivity detection, calibrated against NaCl standards. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature (700-800 C) ashing and weighing of the cooled crucible. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary apparatus per USP <741>. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity of sample against standard white background under controlled lighting per USP <135>. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light by chiral centers in solution using sodium D-line (589 nm) at specified concentration and temperature. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution of solid particles in suspension using Mie scattering theory and calibrated instrument per ISO 13320. |
