Quality Control

Our production of 3-Chloro-5-Ethyl-2-Methoxybenzaldehyde adheres to stringent quality management protocols. Each batch is characterized using advanced analytical techniques including HPLC, GC, NMR, and IR spectroscopy to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment. We support cGMP-compliant manufacturing for pharmaceutical applications and can tailor purity grades to meet specific project requirements, from research (95%+) to high-purity (98%+) standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from strong oxidizing agents and bases.
