Chemical Structure
Description
Fmoc-D-homoArg(Et)2-OH HCl (CAS 2098497-24-4), molecular formula C26H34N4O4HCl and molecular weight 503.04 g/mol, is a CATO reference standard with documented purity and traceability.
Fmoc-D-homoArg(Et)2-OH HCl (C26H34N4O4HCl) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 Fmoc-D-homoArg(Et)2-OH HCl 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.
