Chemical Structure
Description
The occurrence of Fmoc-Pro-Pro-OH is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Fmoc-Pro-Pro-OH (CAS 129223-22-9), a certified reference material (molecular formula C25H26N2O5, MW 434.48 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Fmoc-Pro-Pro-OH is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 434.48 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Fmoc-Pro-Pro-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.
