Manufacturing Quality Control of L-HYDROXYBUTANEDIOIC ACID DISODIUM SALT
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (L-malic acid sodium content) | Acid-base titration | Quantifies sodium L-malate by neutralization with standardized HCl using phenolphthalein or potentiometric endpoint detection. |
| Loss on drying | Gravimetric method (oven drying) | Measures weight loss after drying at 105 C for 2 hours to determine volatile content including moisture and residual solvents. |
| pH (1% aqueous solution) | pH potentiometry | Determines hydrogen ion activity in a 1% w/v aqueous solution using calibrated pH electrode and buffer standards. |
| Heavy metals (as Pb) | Colorimetric sulfide precipitation | Compares sample color intensity after reaction with thioacetamide under controlled pH to lead standard solutions. |
| Arsenic | Gutzeit method | Converts arsenic to arsine gas, which reacts with mercuric bromide paper to form a colored stain proportional to arsenic concentration. |
| Chloride | Argentometric titration (Mohr method) | Titrates chloride ions with standardized silver nitrate using potassium chromate indicator; endpoint signaled by red Ag2CrO4 precipitate. |
| Sulfate | Barium sulfate gravimetry | Precipitates sulfate as BaSO4 under acidic conditions, followed by filtration, drying, and weighing of the precipitate. |
| Iron | UV-Vis spectrophotometry (1,10-phenanthroline) | Forms orange-red Fe(II)-phenanthroline complex; absorbance measured at ~510 nm for quantitative determination. |
| Residue on ignition | Gravimetric method (muffle furnace) | Measures non-volatile inorganic residue remaining after incineration at 600-700 C. |
| Specific optical rotation | Polarimetry | Measures rotation of plane-polarized light by chiral L-malate anion in solution at specified concentration, path length, and temperature. |
| Microbial limits | Membrane filtration and plate count | Filters sample through membrane, incubates on appropriate agar media, and enumerates colony-forming units (CFUs) for total aerobic microbes and absence of specified pathogens. |
| Particle size distribution | Laser diffraction | Analyzes scattered laser light intensity pattern to calculate volume-based particle size distribution in dry or dispersed powder samples. |
