Manufacturing Quality Control of 149353-23-1
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reverse-phase HPLC with UV detection at 210–230 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and detection of structurally similar impurities (e.g., mono-/di-de-tert-butyl analogues, hydrolysis products) using gradient RP-HPLC and UV monitoring. |
| Residual Solvents | GC-FID | Identification and quantification of residual solvents (e.g., acetonitrile, methanol, DMF) by gas chromatography with flame ionization detection against calibrated standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric determination of water based on the stoichiometric reaction between iodine, sulfur dioxide, and water in anhydrous pyridine/methanol medium. |
| Heavy Metals (Pb, Cd, Ni, Fe, Cu) | ICP-MS | Multi-element quantification of trace metals after acid digestion, using inductively coupled plasma mass spectrometry for sub-ppt sensitivity. |
| Residual Bromide (Br⁻) | Ion Chromatography (IC) | Separation and conductivity detection of bromide ions using anion-exchange column with carbonate/bicarbonate eluent. |
| Acid Value | Acid-Base Titration | Neutralization of free carboxylic acid groups with standardized NaOH solution using phenolphthalein or potentiometric endpoint detection. |
| Residual tert-Butyl Cation Derivatives | GC-MS | Detection and semi-quantification of volatile tert-butyl-containing degradation products (e.g., isobutylene, tert-butanol) via headspace GC coupled to mass spectrometry. |
| Chiral Purity | Chiral HPLC | Enantiomeric excess assessment using a chiral stationary phase (e.g., Chiralpak AD-H) and UV detection, confirming absence of racemization during synthesis. |
| Particle Size Distribution | Laser Diffraction | Measurement of dry or wet dispersed particle size via light scattering analysis, reporting D10, D50, D90 values per ISO 13320. |
| Microbial Contamination | Membrane Filtration & Plate Count | Enumeration of aerobic microorganisms following filtration, membrane transfer to TSA agar, and incubation per USP <61>. |
