Quality Control

Our production of 1H-Indene-2-Carboxaldehyde, 2,3-Dihydro-1-Methyl-, (1S,2R)- (9Ci) adheres to stringent quality protocols to ensure batch-to-batch consistency and high chiral purity. Each lot is characterized using advanced analytical techniques including chiral HPLC, NMR, and GC-MS. A comprehensive Certificate of Analysis (COA) detailing identity, purity, enantiomeric excess, and impurity profile is provided with every shipment, supporting cGMP and ISO 9001 compliant workflows for our global partners.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C) in a cool, dry, and well-ventilated area. Due to its sensitivity to oxidation, the container should be kept sealed after each use to minimize exposure to air.
