Quality Control

Our m-Cresolindophenol Sodium Salt is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including identification, assay, and impurity profiling, to meet exacting standards for research and industrial use. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with specified parameters.

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 nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect stability and performance.
