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 MeOSuc-Ala-Ala-Pro-Ala-chloromethylketone.
MeOSuc-Ala-Ala-Pro-Ala-chloromethylketone (CAS 111682-13-4) is a high-purity analytical reference standard with the molecular formula C20H31ClN4O7 and a molecular weight of 474.94 g/mol.
The molecular framework of MeOSuc-Ala-Ala-Pro-Ala-chloromethylketone (C20H31ClN4O7) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 MeOSuc-Ala-Ala-Pro-Ala-chloromethylketone 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.
