Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 477.01 g/mol gives GSK-2269557 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
GSK-2269557 (CAS 1254036-77-5), molecular formula C26H28N6OHCl and molecular weight 477.01 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of GSK-2269557 (C26H28N6OHCl) is characterized by a steroid 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 GSK-2269557 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.
