Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 468.49 g/mol gives PF 04217903 Mesylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
PF 04217903 Mesylate (CAS 956906-93-7), molecular formula C19H16N8OCH4O3S and molecular weight 468.49 g/mol, is a CATO reference standard with documented purity and traceability.
PF 04217903 Mesylate (C19H16N8OCH4O3S) contains a flavonoid core, an amide group, a sulfone 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), PF 04217903 Mesylate 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.
