Quality Control

Our production of 1-(2-Butylsulfonyloxypropoxysulfonyl)Butane adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including chromatography (HPLC/GC) and spectroscopic methods (NMR, IR), to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical parameters are provided with each shipment. We support customer audits and can tailor specifications to meet specific GMP or ISO guided project requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after initial opening to prevent degradation. Keep away from heat, sparks, and open flame.
