Manufacturing Quality Control of DIBENZYL MALONATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 210-230 nm, based on peak area comparison against a certified reference standard. |
| Appearance | Visual Inspection | Assessment of physical state and color by observation in a clear glass container under controlled white light against a white background. |
| Color (APHA) | Colorimeter or Visual Comparison | Measurement of yellowness intensity by comparing sample solution to APHA color standards using spectrophotometric or visual matching techniques. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine, sulfur dioxide, and base in methanol/pyridine solvent to quantify water via stoichiometric reaction. |
| Acid Value | Acid-Base Titration | Neutralization of free carboxylic acid groups with standardized potassium hydroxide ethanol solution, detected potentiometrically or with phenolphthalein. |
| Residue on Ignition | Gravimetric Analysis | Heating sample at 750-800 C to constant weight and measuring non-volatile inorganic residue as percentage of original mass. |
| Heavy Metals (as Pb) | AAS or ICP-OES | Atomic absorption spectroscopy or inductively coupled plasma optical emission spectroscopy after acid digestion to quantify total heavy metal content. |
| Chloride Content | Potentiometric Titration | Titration with silver nitrate using silver electrode detection of endpoint based on formation of insoluble silver chloride. |
| Related Substances | HPLC-DAD | Separation and identification of impurities using gradient HPLC with diode-array detection, relative to main peak area and retention time. |
| Melting Point | Capillary Melting Point Apparatus | Thermal determination of solid-to-liquid transition range using calibrated capillary apparatus per USP/EP guidelines. |
| Density | Digital Density Meter | Measurement of mass per unit volume at 20 C using oscillating U-tube principle with temperature-controlled Peltier system. |
| Refractive Index | Refractometer | Determination of light bending ratio at 20 C using sodium D-line (589 nm) and automatic temperature compensation. |
