Description
CATO supplies DSPE-PEG(2000) Cyanur (CAS 1246304-74-4), a certified reference material (molecular formula C49H87Cl2N5O54PC2H4CH4, MW 1756.19 g/mol) for analytical method development and quality control.
DSPE-PEG(2000) Cyanur (C49H87Cl2N5O54PC2H4CH4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), DSPE-PEG(2000) Cyanur meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
