Manufacturing Quality Control of Cholesteryl chloride
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 205 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time matching and threshold limits per ICH Q3B. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify volatile organic solvents (e.g., chloroform, methanol) against calibrated standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine generation in pyridine-free reagent; measures water by stoichiometric reaction with iodine and sulfur dioxide. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (Pb, Cd, Hg, As) after acid digestion, using isotopic detection with high sensitivity and low detection limits. |
| Chloride Ion | Ion Chromatography | Separation of chloride anions on an anion-exchange column with conductivity detection; quantified via external calibration curve. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, using calibrated digital apparatus per USP <741>. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passed through a solution; indicates chiral purity and identity confirmation. |
| Residue on Ignition | Gravimetric Analysis | Weighing residue remaining after high-temperature ashing (700–800 C) to determine inorganic ash content. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity to calculate volume-based particle size distribution in dispersed dry or wet sample. |
| pH of Aqueous Suspension | pH Meter | Measurement of hydrogen ion activity in a defined suspension (e.g., 1% w/v in water) using calibrated glass electrode. |
| Microbial Contamination | Membrane Filtration | Quantitative recovery and enumeration of aerobic microorganisms from a filtered sample, followed by incubation on TSA agar per USP <61>. |
