Manufacturing Quality Control of 1,15-PENTADECANEDIOL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies 1,15-pentadecanediol peak area relative to internal/external standard using calibrated response factors. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol/pyridine 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 Back-Titration | Measures total hydroxyl groups via acetic anhydride esterification; excess anhydride hydrolyzed and titrated with NaOH. |
| Color (APHA) | Visual Comparison or Spectrophotometry at 455 nm | Evaluates yellowness by comparing sample color to APHA platinum-cobalt standards or measuring absorbance at 455 nm. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Determines non-volatile inorganic residue after heating sample to 700-800 C in a muffle furnace and weighing the ash. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals (expressed as lead) by atomization in flame or graphite furnace and absorption measurement at characteristic wavelengths. |
| Chloride Content | Ion Chromatography (IC) or Potentiometric Titration | Separates and quantifies chloride ions via conductivity detection (IC) or silver nitrate titration with silver electrode endpoint detection. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method per USP/Ph. Eur. guidelines. |
| Appearance | Visual Inspection | Assesses physical state, clarity, and presence of particulates or phase separation against specified criteria under controlled lighting. |
| Volatile Impurities | Headspace Gas Chromatography (HS-GC) | Detects low-boiling organic impurities (e.g., solvents, aldehydes) by analyzing vapor phase above heated sample. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after charring with sulfuric acid and subsequent ignition; reflects sulfate-forming impurities. |
