Chemical Structure
Description
As a certified reference material (CRM), (Leu31,Pro3?)-Neuropeptide Y (porcine) trifluoroacetate salt 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.
CATO supplies (Leu31,Pro3?)-Neuropeptide Y (porcine) trifluoroacetate salt (CAS 125580-28-1), a certified reference material (molecular formula C190H286N54O56C2HF3O2, MW 4336.72 g/mol) for analytical method development and quality control.
(Leu31,Pro3?)-Neuropeptide Y (porcine) trifluoroacetate salt (C190H286N54O56C2HF3O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine 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 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.
