Manufacturing Quality Control of 154862-43-8
| Test Item | Common Test Method | Method Overview |
|---|---|---|
| Purity | High-Performance Liquid Chromatography (HPLC) | Uses a C18 reversed-phase column with gradient elution of acetonitrile/water or methanol/water, and UV detection at 254 nm. Purity is calculated by peak area normalization, effectively separating unreacted raw materials, intermediates, and degradation products. |
| Structural Confirmation | Nuclear Magnetic Resonance Spectroscopy (¹H NMR, ¹³C NMR) | Samples are dissolved in deuterated chloroform (CDCl₃) or deuterated dimethyl sulfoxide (DMSO-d₆). Proton and carbon NMR spectra confirm the substitution pattern of the benzene ring, spirocyclic structure, and characteristic P–O–C bond signals, verifying molecular framework and substituent positions. |
| Phosphorus Content | Ammonium Molybdate Spectrophotometry / ICP-OES | Sample is digested with concentrated nitric acid and hydrogen peroxide, converting phosphorus to phosphate. Phosphate reacts with ammonium molybdate to form phosphomolybdic heteropoly acid, and absorbance is measured at 810 nm; alternatively, phosphorus content is directly determined by Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) for quantitative control. |
| Thermal Stability | Thermogravimetric Analysis (TGA) | Heating from 25°C to 600°C at a rate of 10°C/min under nitrogen or air atmosphere to obtain mass loss curve. Decomposition temperature (Td) and residual char yield are evaluated to ensure thermal resistance meets flame retardant application requirements. |
| Melting Point/Range | Melting Point Apparatus | Determined using capillary method or automatic melting point instrument. Typical melting range is approximately 150–170°C (literature value), used as an initial indicator of crystalline purity and batch consistency. |
| Moisture Content | Karl Fischer Titration (KFT) | Measures trace moisture in samples using coulometric or volumetric methods (typically required <0.1%). Prevents adverse effects of moisture on compatibility and long-term stability in polymer applications. |
| Impurity Profile | LC-MS (Liquid Chromatography-Mass Spectrometry) | After HPLC separation, analytes are ionized via electrospray ionization (ESI) and detected by MS to obtain molecular ion peaks [M+H]⁺ or [M+Na]⁺, enabling identification of structurally related impurities such as mono-substituted compounds, hydrolysis products, and oxidation by-products. |
| Appearance and Color | Visual Inspection + Color Measurement | Observe physical form (white to pale yellow crystalline powder); use colorimeter or colorimetric methods (e.g., APHA color scale) to quantify yellowness index, ensuring visual quality meets industrial standards. |
| Solubility | Solubility Testing | Determine solubility at room temperature in common solvents (e.g., toluene, acetone, ethanol, ethyl acetate, water) to verify dispersibility in polymer processing, serving as an auxiliary parameter for process control. |
| Residual Solvents | Gas Chromatography (GC) | Use headspace or direct injection GC-FID to detect residual organic solvents (e.g., toluene, ethanol, acetone) from manufacturing processes, complying with ICH Q3C guidelines. |
