Manufacturing Quality Control of 4-Hydrazinylbenzoic acid
| Detection Item | Common Testing Methods | Method Overview |
|---|---|---|
| Purity | High-Performance Liquid Chromatography (HPLC) | Uses reversed-phase chromatographic columns with UV detection (e.g., 254 nm) to quantify the main component peak area and calculate purity percentage. Suitable for high-sensitivity and high-resolution separation and analysis of impurities and the main component. |
| Content Determination | HPLC External Standard Method / Acid-Base Titration Method | HPLC External Standard Method: Calibration curve established using reference standard for quantitative determination; Acid-Base Titration Method: Utilizes carboxylic acid groups for titration in aqueous or non-aqueous media, calculating content accordingly. |
| Related Substances (Impurities) | HPLC Gradient Elution Method | Separates main peak from potential impurities using gradient elution program; unknown impurities identified using DAD or MS detectors. Impurity levels calculated by area normalization or self-reference method. |
| Moisture Content | Karl Fischer Water Titration Method | Uses coulometric or volumetric Karl Fischer reagent to titrate trace moisture in samples, suitable for precise determination of trace water in organic compounds. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatilized solvents in heated samples enter the gas phase, separated by capillary column, and quantified using FID or MS detectors (e.g., methanol, ethanol, DMF). |
| Heavy Metals | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) or Atomic Absorption Spectroscopy (AAS) | After sample digestion, elements such as lead, arsenic, cadmium, and mercury are measured, ensuring compliance with pharmacopoeial or ICH Q3D limits. |
| Melting Point | Capillary Melting Point Determination | Measured using a digital melting point apparatus by observing initial and final melting temperatures during heating, used to assess compound purity and crystal form consistency. |
| Appearance and Color | Visual Inspection / UV-Visible Spectrophotometry | Visually inspected for white to off-white crystalline powder; UV-Vis spectroscopy used optionally to assess colored impurities by scanning solution absorbance at 400–700 nm. |
| pH (Solution) | pH Meter Measurement | Sample dissolved into a specified concentration (e.g., 1%), pH measured using a calibrated pH meter to evaluate acidity/basicity stability and salt form influence. |
| Residue on Ignition | Gravimetric Method | Sample ignited at high temperature (600–800°C) until constant weight; residual inorganic mass is weighed, used to assess inorganic impurities or catalyst residues. |
