Quality Control

Our production of Carbamic Acid, (Tetrahydro-4-Hydroxy-3-Thienyl)-, Phenylmethyl Ester, cis- (9Ci) adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity suitable for research and development applications. All materials are characterized using advanced analytical techniques including HPLC, GC, NMR, and IR spectroscopy. A comprehensive Certificate of Analysis (COA) detailing purity, chiral purity (enantiomeric excess), and impurity profiles is provided with each shipment to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
