Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 463.48 g/mol gives Boc-Orn(Z)-Osu distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Boc-Orn(Z)-Osu (CAS 57225-25-9) is a high-purity analytical reference standard with the molecular formula C22H29N3O8 and a molecular weight of 463.48 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Boc-Orn(Z)-Osu is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 463.48 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
