Manufacturing Quality Control of 3,5-Di-tert-butylcatechol
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reversed-phase HPLC with UV detection at 280 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time matching and relative response factors. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., toluene, heptane) based on calibrated external standards. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine generated electrochemically to react stoichiometrically with water in the sample. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification after acid digestion, measuring emission intensities of metal-specific wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation of anions on an ion-exchange column with conductivity detection; quantified against chloride calibration standards. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid transition temperature using controlled heating and visual observation of meniscus collapse. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under standardized white light and against reference samples. |
| Residue on Ignition | Gravimetric Analysis | Weighing residue remaining after high-temperature ashing (700-800 C) to determine inorganic ash content. |
| Acid Value | Acid-Base Titration | Titration with standardized KOH ethanol solution using phenolphthalein indicator; measures carboxylic acid or phenolic impurities. |
| Bulk Density | Tap Density Measurement | Mass per unit volume after controlled tapping of a known mass in a graduated cylinder per USP <616>. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity patterns to calculate volume-based particle size distribution in dispersed dry powder. |
