Quality Control

Our production of Methyl 1-Phenylethanesulfonate adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity, GC for residual solvents, and NMR/IR for structural confirmation. We provide detailed Certificates of Analysis (COA) with every shipment, ensuring traceability and compliance with your research or production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
