Chemical Structure
Description
COP-1 (CAS 28704-27-0), molecular formula C9H11NO3C5H9NO4C6H14N2O2C3H7NO2 and molecular weight 563.61 g/mol, is a CATO reference standard with documented purity and traceability.
COP-1 (C9H11NO3C5H9NO4C6H14N2O2C3H7NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
