Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 470.69 g/mol gives H-Cys-psi(CH2NH)Val-psi(CH2NH)Phe-Met-OH distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
H-Cys-psi(CH2NH)Val-psi(CH2NH)Phe-Met-OH (CAS 149759-96-6) is a high-purity analytical reference standard with the molecular formula C22H38N4O3S2 and a molecular weight of 470.69 g/mol.
The molecular framework of H-Cys-psi(CH2NH)Val-psi(CH2NH)Phe-Met-OH (C22H38N4O3S2) is characterized by a steroid core, 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. 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), H-Cys-psi(CH2NH)Val-psi(CH2NH)Phe-Met-OH 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.
