Manufacturing Quality Control of 2-PENTYNOIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies 2-pentynoic acid peak area against a calibration curve using an internal or external standard. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration based on the reaction of iodine with water in a pyridine-methanol solvent system. |
| Acid Value | Acid-Base Titration with NaOH | Determines free carboxylic acid content by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing at 700-800 C. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals (e.g., Pb, Cd, Hg, As) after acid digestion by measuring atomic absorption at element-specific wavelengths. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions using an anion-exchange column and conductivity detection. |
| Sulfate Impurity | Ion Chromatography (IC) | Separates and quantifies sulfate ions using an anion-exchange column and conductivity detection. |
| Related Substances | High-Performance Liquid Chromatography (HPLC) with UV detection | Identifies and quantifies structurally related impurities (e.g., isomers, degradation products) using reversed-phase separation and UV absorbance. |
| Color | Visual Comparison or Spectrophotometry (APHA/Pt-Co scale) | Evaluates yellowness intensity by comparing sample color to platinum-cobalt standard solutions or measuring absorbance at 430 nm. |
| Density | Digital Density Meter | Determines mass per unit volume at specified temperature (e.g., 20 C) using oscillating U-tube principle. |
| Refractive Index | Refractometry | Measures bending of light through liquid sample at specified temperature (e.g., 20 C) using Abbe refractometer. |
| Flash Point | Pensky-Martens Closed Cup Tester | Determines lowest temperature at which vapors ignite under controlled heating and ignition source conditions. |
