Manufacturing Quality Control of 1,2-Hexadecanediol
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies 1,2-hexadecanediol peak area relative to a calibration curve using an internal or external standard. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration based on the stoichiometric reaction of iodine with water in pyridine/methanol medium. |
| Acid Value | Acid-Base Titration with NaOH | Determines free carboxylic acid impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Hydroxyl Value | Acetylation followed by Titration | Measures total hydroxyl groups via acetylation with acetic anhydride, then back-titration of unreacted anhydride with NaOH. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Compares sample color to APHA platinum-cobalt standards; spectrophotometric version measures absorbance at 430 nm. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method per ASTM D1560. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing (700-800 C) and weighing. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after acid digestion by measuring absorbance of metal-specific atomic vapor. |
| Chloride Content | Ion Chromatography (IC) or Potentiometric Titration | Separates and quantifies chloride ions using conductivity detection (IC) or silver nitrate titration with potentiometric endpoint. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after sulfuric acid treatment and incineration, per USP <281>. |
| Related Substances | High-Performance Liquid Chromatography (HPLC) with UV detection | Separates and quantifies structurally related impurities (e.g., monoalcohols, ketones, epoxides) using reverse-phase C18 column and UV detection at 210 nm. |
| Bulk Density | Graduated Cylinder Method | Measures mass per unit volume of freely settled powder using standardized cylinder and balance per ASTM D1895. |
