Chemical Structure
Description
The occurrence of H-Arg-Arg-Arg-OH acetate salt is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
H-Arg-Arg-Arg-OH acetate salt (CAS 6418-87-7), molecular formula C18H38N12O4C2H4O2 and molecular weight 546.63 g/mol, is a CATO reference standard with documented purity and traceability.
H-Arg-Arg-Arg-OH acetate salt (C18H38N12O4C2H4O2) contains a steroid core, 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. 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 H-Arg-Arg-Arg-OH acetate salt 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.
