Quality Control

Our Acetonitrile is produced under stringent quality management systems. We offer various grades, including HPLC, Pharmaceutical, and Technical, each meeting specific industry requirements. Certificates of Analysis (COA) are provided with every shipment, detailing key parameters such as purity, water content, and UV transmittance. Our quality assurance protocols are designed to ensure batch-to-batch consistency and compliance with relevant pharmacopeial standards (e.g., USP, EP) where applicable.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Due to its highly volatile nature, keep containers tightly sealed when not in use. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep away from strong oxidizing agents, strong acids, and strong bases.
