Quality Control

Our Carbostyril 124 n-Carboxyethyl Methanethiosulfonate is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity for research applications. Each lot undergoes comprehensive analytical characterization, including HPLC, NMR, and mass spectrometry, to confirm identity and purity. Certificates of Analysis (COA) with detailed chromatographic data are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C or as indicated on the label or COA. This material is hygroscopic (moisture-sensitive) and should be handled under anhydrous conditions to maintain stability. Allow the sealed container to equilibrate to room temperature before opening to minimize moisture ingress.
