Quality Control

Our production of 4-Bromo-1-(4-Fluorophenyl)-1H-Pyrazole adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC, NMR, and GC-MS, to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with each shipment, confirming compliance with customer specifications and relevant industry standards for fine chemical intermediates.

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 (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
