Description

Compared with other compounds in its class, the molecular weight of 329.40 g/mol gives (S)-2-Amino-N-((S)-1-amino-5-guanidino-1-oxopentan-2-yl)-5-guanidinopentanamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(S)-2-Amino-N-((S)-1-amino-5-guanidino-1-oxopentan-2-yl)-5-guanidinopentanamide (CAS 63277-12-3) is a high-purity analytical reference standard with the molecular formula C12H27N9O2 and a molecular weight of 329.40 g/mol.

The molecular framework of (S)-2-Amino-N-((S)-1-amino-5-guanidino-1-oxopentan-2-yl)-5-guanidinopentanamide (C12H27N9O2) is characterized by an amino-acid-derived structure, an amide 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.
