(Leu?,D-Trp22,Tyr2?)-Somatostatin-28 CAS 77909-99-0

Description

Compared with other compounds in its class, the molecular weight of 3146.56 g/mol gives (Leu?,D-Trp22,Tyr2?)-Somatostatin-28 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies (Leu?,D-Trp22,Tyr2?)-Somatostatin-28 (CAS 77909-99-0), a certified reference material (molecular formula C138H209N41O40S2, MW 3146.56 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, (Leu?,D-Trp22,Tyr2?)-Somatostatin-28 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 3146.56 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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), (Leu?,D-Trp22,Tyr2?)-Somatostatin-28 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.
