Manufacturing Quality Control of (S)-(+)-1,1'-Binaphthyl-2,2'-diyl hydrogenphosphate
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Chemical Purity | High-Performance Liquid Chromatography (HPLC) | Uses a reversed-phase C18 column with gradient elution of methanol-water or acetonitrile-water. Detection is performed using a UV detector (254 nm) to quantify the main component and evaluate impurity peak areas for purity calculation. Suitable for separating chiral isomers and degradation products. |
| Chiral Purity (Enantiomeric Excess, ee Value) | Chiral High-Performance Liquid Chromatography (Chiral HPLC) | Employs chiral stationary phase columns (e.g., Chiralpak AD-H, OD-H, or Chiralcel OB-H) with n-hexane-isopropanol as the mobile phase. The ratio of S- and R-enantiomers is quantified by comparing retention times with reference standards to calculate the ee value. |
| Water Content | Karl Fischer Titration | Uses a reagent composed of iodine, sulfur dioxide, pyridine, and methanol that reacts quantitatively with water. The endpoint is determined potentiometrically or amperometrically to accurately measure trace moisture levels, compliant with pharmacopeial requirements (e.g., USP/EP). |
| Melting Point | Melting Point Apparatus | Determines the melting range using capillary method or automated melting point instrument. Comparison with literature values or reference standards helps assess crystal purity and consistency of crystalline form. |
| UV Absorption Characteristics | Ultraviolet-Visible Spectrophotometry (UV-Vis) | Scans absorption spectrum in the 200–400 nm wavelength range to identify maximum absorption wavelength (λmax), used for qualitative identification and quantitative analysis (in conjunction with HPLC). |
| Infrared Functional Group Identification | Fourier Transform Infrared Spectroscopy (FT-IR) | Obtains infrared spectra via KBr pellet or ATR technique to identify characteristic absorption peaks such as P=O, P–O–C, aromatic C=C, etc., confirming molecular structure integrity and detecting impurity functional groups. |
| Heavy Metal Residues | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After acid digestion of the sample, AAS or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) is used to determine residual levels of heavy metals such as Pb, Cd, Hg, As, Cu, meeting ICH Q3D or pharmacopeial limits. |
| Residual Solvents | Gas Chromatography (GC) | Uses headspace or direct injection with a capillary column (e.g., DB-624) and FID detector to detect residual organic solvents such as ethanol, acetone, dichloromethane, and acetonitrile, complying with ICH Q3C guidelines. |
| Thermal Stability / Decomposition Temperature | Thermogravimetric Analysis (TGA) | Heats the sample under nitrogen or air atmosphere at a programmed rate, monitoring mass change versus temperature to assess onset of thermal decomposition and weight loss behavior, useful for evaluating material stability and setting storage conditions. |
| Crystal Form Identification | X-Ray Powder Diffraction (XRPD) | Measures the diffraction pattern of the sample and compares it with standard patterns to confirm the presence of polymorphism and ensure physical property consistency across batches. |
| Chloride Ions / Inorganic Anions | Ion Chromatography (IC) | Uses an anion-exchange column with conductivity detection to measure inorganic impurities such as Cl⁻, SO₄²⁻ that may be introduced during manufacturing, applicable for controlling inorganic salt residues in active pharmaceutical ingredients. |
