Manufacturing Quality Control of 16-HYDROXYHEXADECANOIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 205 nm. |
| Identity Confirmation | FTIR Spectroscopy | Verification by matching characteristic functional group absorption bands (e.g., O-H, C=O, C-O) to reference spectrum. |
| Acid Value | Acid-Base Titration | Determination of free carboxylic acid content via titration with standardized KOH solution using phenolphthalein indicator. |
| Water Content | Karl Fischer Titration | Electrochemical quantification of water based on iodine-sulfur dioxide reaction in pyridine-methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after controlled high-temperature ashing and weighing. |
| Heavy Metals (as Pb) | AAS (Flame or Graphite Furnace) | Atomic absorption measurement of total heavy metal content after acid digestion and calibration with lead standards. |
| Residual Solvents | GC-FID | Separation and quantification of volatile organic solvents (e.g., methanol, ethyl acetate) using capillary GC with flame ionization detection. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, compared to reference standard. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral centers in solution at specified concentration and wavelength. |
| Color (APHA) | Visual Comparison or Colorimeter | Evaluation of yellowness intensity by matching to APHA platinum-cobalt standard solutions or instrumental measurement. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or dispersed particle size based on angular scattering pattern of laser beam. |
| Microbial Limits | Membrane Filtration and Plate Count | Enumeration of aerobic microorganisms after filtration, membrane transfer to agar media, and colony counting. |
