Quality Control

Every batch of 5-(4-Carboxy-2-Nitrophenoxy)Isophthalic Acid is manufactured and tested under a strict quality management system. We ensure compliance with rigorous internal specifications, which are designed to meet the high standards required for advanced synthetic applications. A comprehensive Certificate of Analysis (COA), detailing purity, identity, and impurity profiles, is provided with each shipment to guarantee traceability and consistency for our global B2B clients.

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 sealed to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
