Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 362.38 g/mol gives Boc-Phe-OSu distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Boc-Phe-OSu (CAS 3674-06-4), molecular formula C18H22N2O6 and molecular weight 362.38 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Boc-Phe-OSu is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 362.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), Boc-Phe-OSu 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.
