Description
CATO supplies 7-(D-苯丙氨酰基-D-苯丙氨酰基-D-亮氨酰基-L-赖氨酰基)-2-乙酰基-2,7-二氮杂螺[3.5]壬烷 (CAS CATO-CPTD788985), a certified reference material (molecular formula C39H57N7O5, MW 703.91 g/mol) for analytical method development and quality control.
7-(D-苯丙氨酰基-D-苯丙氨酰基-D-亮氨酰基-L-赖氨酰基)-2-乙酰基-2,7-二氮杂螺[3.5]壬烷 (C39H57N7O5) 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 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), 7-(D-苯丙氨酰基-D-苯丙氨酰基-D-亮氨酰基-L-赖氨酰基)-2-乙酰基-2,7-二氮杂螺[3.5]壬烷 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.
