Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards and batch-to-batch consistency. We employ advanced analytical techniques including HPLC, titration, and spectroscopic methods to verify identity, purity, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing all test results is available for every batch upon request, supporting your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture which can lead to caking or decomposition.
