Quality Control

Our Sodium Dihydrogen Phosphate is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets the required specifications for purity, identity, and performance. Certificates of Analysis (COA) are provided and the product can be manufactured to meet various standards, including FCC and USP/EP grades, upon request.

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); containers must be kept tightly sealed to prevent absorption of atmospheric moisture and caking.
