Manufacturing Quality Control of L-(-)-ARABITOL
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Identification Test | Infrared Spectroscopy (IR) | Determine the infrared absorption spectrum of the sample and compare it with the standard spectrum to confirm the characteristic functional groups (such as hydroxyl and C–O) of L-(-)-Arabitol. |
| Specific Rotation Determination | Measure the optical rotation of the sample at a specific wavelength (usually the sodium D line, 589 nm) and temperature using a polarimeter, and calculate the specific rotation to verify its optical activity conforms to the L-(-)-configuration requirement (typically negative value). | |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Use a differential refractive index detector (RID) or evaporative light scattering detector (ELSD), separate the sample using an appropriate chromatographic column (such as an amino column or carbohydrate-specific column), and quantify L-(-)-Arabitol by external or internal standard method. |
| Gas Chromatography (GC) | After derivatization (e.g., silylation), the sample is separated using a capillary column and detected by a flame ionization detector (FID). The content is calculated by external standard method, suitable for high-purity sample analysis. | |
| Drying Loss | Drying Loss Method | Dry the sample at a specified temperature (e.g., 105°C) until constant weight is achieved, then calculate the percentage of mass loss to assess the moisture and volatile substance content. |
| Ignited Residue | High-Temperature Ashing Method | Carbonize the sample first, then incinerate it at high temperature (usually 700–800°C) until constant weight is reached. Weigh the residual inorganic material to control the total amount of inorganic impurities. |
| Heavy Metals | Thioacetamide Method (or Atomic Absorption Spectroscopy) | Under acidic conditions, heavy metal ions react with thioacetamide to form colored precipitates, which are compared with standard lead solution; alternatively, atomic absorption spectroscopy (AAS) can be used to directly determine the content of heavy metals such as lead and arsenic. |
| Residual Solvents | Gas Chromatography (GC) | Use headspace injection or direct injection, separate the residual solvents (such as methanol, ethanol, acetone) using a polar or non-polar capillary column, and detect them with a flame ionization detector (FID). The limits are controlled according to ICH guidelines. |
| Microbial Limit | Plate Count Method / Membrane Filtration Method | Perform aerobic bacterial total count, mold and yeast count, as well as control bacteria (such as Escherichia coli, Salmonella) according to the Chinese Pharmacopoeia or relevant standards to ensure microbial contamination is within acceptable limits. |
| pH Value | pH Meter Measurement | Prepare a solution of certain concentration (e.g., 10%) and measure its pH value using a calibrated pH meter to evaluate whether the acidity or alkalinity falls within the specified range (usually close to neutral). |
