Industrial Applications of 2-Methylbenzophenone
| Industry | Application | Process |
|---|---|---|
| Coatings and Inks Industry | Photoinitiator for ultraviolet (UV) curable coatings and inks | Absorbs UV energy to generate free radicals, initiating polymerization and crosslinking of unsaturated resin systems |
| Plastics and Polymers Industry | Photostabilizer and ultraviolet absorber for plastic products | Incorporated into polymer matrices to absorb harmful UV radiation and dissipate it as heat, thereby retarding photodegradation |
| Chemical Synthesis | Synthetic intermediate for pharmaceuticals and fine chemicals | Serves as an aryl ketone scaffold in organic synthesis reactions to construct target molecular frameworks |
Manufacturing Quality Control of 2-Methylbenzophenone
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantitative determination based on peak area comparison against a certified reference standard using a non-polar capillary column. |
| Appearance | Visual Inspection | Assessment of physical state and clarity under controlled lighting against specified criteria for color and particulate matter. |
| Color (APHA) | APHA Color Scale (Visual or Spectrophotometric) | Comparison of sample solution color intensity to APHA platinum-cobalt standard solutions using visual matching or UV-Vis absorbance at 430 nm. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid phase transition temperature range using calibrated capillary tube method per USP <741>. |
| Loss on Drying | Gravimetric Method (Oven Drying) | Measurement of mass loss after drying at 105 C for 2 hours, indicating volatile impurities and residual solvents. |
| Residue on Ignition | Sulfated Ash (Gravimetric) | Determination of inorganic residue after charring and incineration at 600 C, followed by sulfuric acid treatment and weighing. |
| Chloride Impurity | Ion Chromatography (IC) or Potentiometric Titration | Quantification of chloride ions via conductivity detection (IC) or silver nitrate titration with potentiometric endpoint detection. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) or ICP-OES | Quantitative measurement of total heavy metals after wet digestion, using flame AAS or ICP-OES with lead-specific calibration. |
| Related Substances | High Performance Liquid Chromatography (HPLC) with UV detection | Separation and quantification of structurally related impurities using reversed-phase C18 column and UV detection at 254 nm. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical determination of water content based on stoichiometric reaction of iodine with water in anhydrous methanol-based reagent. |
| Acid Value | Acid-Base Titration (NaOH standard solution) | Neutralization of acidic impurities with standardized sodium hydroxide solution using phenolphthalein indicator or potentiometric endpoint. |
| Organic Volatile Impurities | Headspace Gas Chromatography (HS-GC) | Detection and quantification of residual solvents (e.g., toluene, acetone) by equilibrium partitioning into headspace followed by GC-FID analysis. |
