Manufacturing Quality Control of 2,6-Naphthalenediol
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area against a certified reference standard using reversed-phase chromatography and UV detection at 280 nm. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration with iodine reagent to determine water content based on stoichiometric reaction with iodine and sulfur dioxide in pyridine/methanol medium. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, indicating purity and identity via comparison to reference value (169-171 C). |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after high-temperature ashing (750-800 C) and subsequent weighing. |
| Heavy Metals (as Pb) | AAS (Flame or Graphite Furnace) | Atomic absorption spectroscopy quantifies total heavy metals by measuring absorbance of ground-state atoms in flame or graphite furnace atomizer. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride anions using anion-exchange column and conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Weight of residue remaining after incineration with sulfuric acid pretreatment, indicating inorganic sulfate impurities. |
| Organic Volatile Impurities | GC-FID | Gas chromatography with flame ionization detection identifies and quantifies residual solvents and volatile organic impurities. |
| Color (APHA) | Visual Comparison or Spectrophotometer | Measurement of yellowness intensity by matching sample solution color to APHA platinum-cobalt standards or measuring absorbance at 430 nm. |
| Acid Value | Acid-Base Titration | Titration with standardized KOH solution to quantify acidic impurities (e.g., naphthoic acids) using phenolphthalein indicator. |
| Iron Content | ICP-OES | Inductively coupled plasma optical emission spectrometry measures iron concentration by detecting characteristic atomic emission lines after plasma atomization. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity as function of angle to calculate size distribution of solid particles in suspension. |
