Quality Control

Our 2-(Phosphonomethyl)-Pentanedioic Acid is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay by titration and identification by FTIR, to ensure it meets precise specifications and is free from significant impurities. Certificates of Analysis (COA) documenting purity, physical characteristics, and other critical parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality.
