H-Leu-Trp-Met-Arg-Phe-OH CAS 67201-39-2

Description

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.

H-Leu-Trp-Met-Arg-Phe-OH (CAS 67201-39-2), molecular formula C37H53N9O6S and molecular weight 751.94 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of H-Leu-Trp-Met-Arg-Phe-OH (C37H53N9O6S) is characterized by a nitrogen-containing heterocyclic scaffold, 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).

CATO manufactures H-Leu-Trp-Met-Arg-Phe-OH 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.
