Chemical Structure
Description
Boc-D-Tyr(2,6-dichloro-Bzl)-OH (CAS 69541-62-4), molecular formula C21H23Cl2NO5 and molecular weight 440.32 g/mol, is a CATO reference standard with documented purity and traceability.
Boc-D-Tyr(2,6-dichloro-Bzl)-OH (C21H23Cl2NO5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), Boc-D-Tyr(2,6-dichloro-Bzl)-OH 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.
