Quality Control

Our production of 2H-Pyran-6-Carboxaldehyde, 3,4-Dihydro-3-Hydroxy-4-Oxo- (9Ci) adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment. We support custom synthesis and can tailor purity grades, typically from 95% to 98%+, to meet specific research or cGMP starting material requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place at 2-8°C for long-term stability. This compound is easily oxidized and moisture-sensitive; allow the container to reach room temperature before opening to minimize condensation and exposure to air.
