Manufacturing Quality Control of Pyrazine-2,5-dicarboxylic acid

Detection Item Common Analytical Method Method Overview
Assay (Purity) HPLC-UV Quantitative determination using reversed-phase HPLC with UV detection at ~220 nm, comparing peak area against a certified reference standard.
Loss on Drying (LOD) Gravimetric Thermogravimetry Mass loss measured after drying at 105 °C for 2 hours under controlled humidity and airflow.
Residue on Ignition (Sulfated Ash) Gravimetric Sulfated Ashing Sample ignited at 700–750 °C after sulfuric acid treatment; residual inorganic ash weighed.
Heavy Metals (as Pb) ICP-OES Multi-element quantification of heavy metals (e.g., Pb, Cd, Hg, As) following acid digestion and plasma excitation.
Chloride Impurity Ion Chromatography (IC) Separation and quantification of chloride anion using suppressed conductivity detection after aqueous extraction.
Sulfate Impurity IC or Barium Sulfate Gravimetry Anion separation by IC or precipitation as BaSO₄ followed by gravimetric measurement.
Water Content Karl Fischer Titration (Coulometric) Electrochemical titration quantifying water via iodine generation proportional to sample moisture content.
Related Substances HPLC-UV (with gradient elution) Detection and quantification of structurally related impurities (e.g., mono-acid intermediates, decarboxylated analogs) using validated HPLC method.
pH (1% aqueous suspension) Potentiometric pH Measurement pH determined in deionized water suspension using calibrated glass electrode.
Melting Point Capillary Melting Point Apparatus Thermal transition temperature measured by observing solid-to-liquid phase change under controlled heating rate.
Particle Size Distribution Laser Diffraction Size distribution analysis based on angular scattering intensity of laser light passing through dispersed particles.
Specific Optical Rotation Polarimetry Measurement of rotation angle of plane-polarized light induced by chiral molecules in solution (if applicable; typically near zero for racemic or achiral batches).
