Quality Control

Our production of 3-(4-tert-Butoxy-Phenyl)-2-Isocyanato-Propionic Acid Methyl Ester adheres to stringent in-process controls to ensure batch-to-batch consistency and high purity. Every lot is fully characterized by HPLC, NMR, and IR spectroscopy. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your quality and regulatory requirements.

Storage

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