Boc-Tyr-OSu CAS 20866-56-2 chemical structure

Description

Boc-Tyr-OSu (CAS 20866-56-2) is a high-purity analytical reference standard with the molecular formula C18H22N2O7 and a molecular weight of 378.38 g/mol.

Boc-Tyr-OSu (C18H22N2O7) contains a flavonoid 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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-Tyr-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.
