Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 437.53 g/mol gives GSK9311 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies GSK9311 (CAS 1923851-49-3), a certified reference material (molecular formula C24H31N5O3, MW 437.53 g/mol) for analytical method development and quality control.
GSK9311 (C24H31N5O3) 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), GSK9311 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
