Chemical Structure

Phe-Lys(Fmoc)-PAB CAS 2149584-03-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 620.74 g/mol gives Phe-Lys(Fmoc)-PAB distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Phe-Lys(Fmoc)-PAB (CAS 2149584-03-0), a certified reference material (molecular formula C37H40N4O5, MW 620.74 g/mol) for analytical method development and quality control.

Phe-Lys(Fmoc)-PAB (C37H40N4O5) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

CATO manufactures Phe-Lys(Fmoc)-PAB under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
