Chemical Structure

D-Lys (11)-Terlipressin CAS CATO-C4X-219331 chemical structure

Description

D-Lys (11)-Terlipressin (CAS CATO-C4X-219331), molecular formula C52H74N16O15S2 and molecular weight 1227.37 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, D-Lys (11)-Terlipressin is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1227.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), D-Lys (11)-Terlipressin 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.
