O-tert-Butyldimethylsilyl-N-methyl-N-t-butoxycarbonyl-L-tyrosine, Methyl Ester CAS 112196-58-4 chemical structure

Description

The occurrence of O-tert-Butyldimethylsilyl-N-methyl-N-t-butoxycarbonyl-L-tyrosine, Methyl Ester is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies O-tert-Butyldimethylsilyl-N-methyl-N-t-butoxycarbonyl-L-tyrosine, Methyl Ester (CAS 112196-58-4), a certified reference material (molecular formula C22H37NO5Si, MW 423.62 g/mol) for analytical method development and quality control.

The molecular framework of O-tert-Butyldimethylsilyl-N-methyl-N-t-butoxycarbonyl-L-tyrosine, Methyl Ester (C22H37NO5Si) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), O-tert-Butyldimethylsilyl-N-methyl-N-t-butoxycarbonyl-L-tyrosine, Methyl Ester 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.
