Description
CATO supplies (Deamino-Cys1,Lys8)-Vasopressin (CAS 2989-84-6), a certified reference material (molecular formula C46H64N12O12S2, MW 1041.22 g/mol) for analytical method development and quality control.
The molecular framework of (Deamino-Cys1,Lys8)-Vasopressin (C46H64N12O12S2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), (Deamino-Cys1,Lys8)-Vasopressin 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.
