Quality Control

Our 4-Methoxycarbonylphenyl Isothiocyanate is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets exacting standards. A detailed Certificate of Analysis (COA) with batch-specific results is provided with every shipment to guarantee traceability and consistency for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its hygroscopic and highly volatile nature, the container must be kept tightly sealed after use to minimize exposure to moisture and prevent evaporation. Keep away from heat, sparks, and open flame.
