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.

CATO supplies L-Alanyl-L-prolyl-L-arginyl-L-leucyl-L-arginyl-L-phenylalanyl-L-tyrosine (CAS 87549-54-0), a certified reference material (molecular formula C44H67N13O9, MW 922.08 g/mol) for analytical method development and quality control.

The molecular framework of L-Alanyl-L-prolyl-L-arginyl-L-leucyl-L-arginyl-L-phenylalanyl-L-tyrosine (C44H67N13O9) is characterized by a nitrogen-containing heterocyclic scaffold, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

CATO manufactures L-Alanyl-L-prolyl-L-arginyl-L-leucyl-L-arginyl-L-phenylalanyl-L-tyrosine 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.
