Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including H-Gly-Pro-Arg-Pro-NH?.
H-Gly-Pro-Arg-Pro-NH? (CAS 126047-75-4) is a high-purity analytical reference standard with the molecular formula C18H32N8O4 and a molecular weight of 424.50 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, H-Gly-Pro-Arg-Pro-NH? is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 424.50 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 H-Gly-Pro-Arg-Pro-NH? 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.
