Quality Control

Our 4-Methylphenyl2,3,4,6-Tetra-o-Acetyl-B-D-Thiogalactopyranoside is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and specific tests for residual solvents and moisture. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all specifications and test results to ensure traceability and compliance with your research or cGMP requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption. For long-term storage, consider storage under an inert atmosphere.
