Manufacturing Quality Control of Thiamine nitrate
| Test Item | Common Test Methods | Method Overview |
|---|---|---|
| Identification | Ultraviolet-Visible Spectrophotometry (UV-Vis) | Utilizes characteristic absorption peaks of thiamine nitrate at specific wavelengths (e.g., around 246 nm, 268 nm, and 300 nm) for qualitative identification. |
| Infrared Spectroscopy (IR) | Confirms molecular structure consistency by comparing sample spectra with standard reference spectra based on functional group vibrational absorption peaks. | |
| Assay | Ultraviolet-Visible Spectrophotometry | Measures absorbance at the maximum absorption wavelength and quantifies thiamine nitrate concentration using a calibration curve. |
| High-Performance Liquid Chromatography (HPLC) | Uses a C18 column with mobile phase such as phosphate buffer-methanol, and UV detection for high-precision quantification. | |
| Loss on Drying | Thermogravimetric Analysis (or Oven Method) | Dries the sample at 105°C to constant weight; calculates moisture and volatile content based on weight loss. |
| Residue on Ignition | Residue on Ignition Test | Sample is ignited at high temperature (500–600°C), and the residue is weighed to assess inorganic impurity content. |
| Solution Clarity and Color | Visual Comparison / Spectrophotometry | The sample solution is compared visually or spectrophotometrically with standard color solutions to determine clarity and whether color meets specifications. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or Sulfide Test | AAS enables precise measurement of heavy metals such as lead and cadmium; sulfide test is a classical colorimetric method used for limit testing. |
| pH Value | pH Meter Method | Dissolve thiamine nitrate in water and measure pH directly using a calibrated pH meter to evaluate acidity or alkalinity. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Separates active ingredient from degradation products (e.g., thiamine degradation compounds) via gradient elution to detect and control impurity levels. |
| Microbial Limits | Microbial Limit Test (Pharmacopoeial Method) | Performs tests according to requirements of the Chinese Pharmacopoeia or international pharmacopoeias, including total aerobic microbial count, mold and yeast count, and specified microorganisms (e.g., Escherichia coli). |
