| Loss on Drying | Gravimetric (Oven Drying) | Mass loss measured after drying sample at 105 C for 2 hours under atmospheric pressure. |
| Residue on Ignition | Gravimetric (Sulfated Ash) | Residue mass determined after charring and incineration at 700-750 C in a muffle furnace. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride anions using suppressed conductivity detection. |
| Heavy Metals (as Pb) | AAS (Flame or Graphite Furnace) | Quantification of total heavy metals by atomic absorption spectroscopy after acid digestion and chelation. |
| Related Substances | HPLC-DAD | Identification and quantification of impurities using HPLC with diode-array detection and relative retention time matching. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration based on the stoichiometric reaction of iodine with water in pyridine-methanol medium. |
| Acid Value | Acid-Base Titration (NaOH) | Neutralization of free carboxylic acid groups with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution at specified concentration and path length. |
| Solubility in Common Solvents | Qualitative Solubility Test | Observation of complete dissolution in specified solvents (e.g., ethanol, acetone, ethyl acetate) at 25 C with gentle agitation. |
