Manufacturing Quality Control of beta-Cyclodextrin methyl ethers
| Test Item | Common Test Methods | Method Overview |
|---|---|---|
| Identification Test | Infrared Spectrophotometry (IR) | Confirm the consistency of functional groups and structural characteristics by comparing the infrared absorption spectrum of the sample with that of the reference standard. |
| Assay | High-Performance Liquid Chromatography (HPLC) | Quantitatively analyze the content of the main component using a reverse-phase or normal-phase chromatographic column with a reference standard, ensuring the purity meets specifications. |
| Degree of Substitution (DS) | Proton Nuclear Magnetic Resonance (¹H-NMR) | Calculate the average methyl substitution degree (DS) by the integral ratio of methyl proton peak to glucose unit proton peak areas. |
| Loss on Drying | Drying to Constant Weight at 105°C | Dry the sample at the specified temperature until constant weight and calculate the percentage of mass loss to assess moisture and volatile content. |
| Residue on Ignition | Muffle Furnace Ashing Method | Weigh the residue after high-temperature (usually 600–800°C) incineration of the sample to evaluate the content of inorganic impurities. |
| Total Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | Determine trace elements such as lead, arsenic, cadmium, and mercury after digestion, ensuring compliance with pharmacopoeia or industry safety standards. |
| Clarity and Color of Solution | Visual Color Comparison / Spectrophotometry | Prepare a solution of specified concentration, observe clarity or measure absorbance at specific wavelengths to assess impurities or degradation products. |
| pH Value | pH Meter Method | Prepare an aqueous solution of specified concentration and directly measure the pH using a calibrated pH meter to ensure the acidity or alkalinity meets formulation requirements. |
| Microbial Limits | Pharmacopoeia Microbiological Testing Methods (e.g., USP/EP/ChP) | Detect total aerobic microbial count, total combined molds and yeasts count, and specified control organisms using membrane filtration or plate count methods, ensuring sterility or low bioburden. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Qualitatively and quantitatively analyze possible residual organic solvents (e.g., methanol, acetone) from the manufacturing process, complying with ICH Q3C guidelines. |
