Chemical Structure

2-hydroxyethyl ((benzyloxy)carbonyl)-L-tryptophanate CAS 642478-72-6 chemical structure

Description

The occurrence of 2-hydroxyethyl ((benzyloxy)carbonyl)-L-tryptophanate is closely related to a flavonoid 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 2-hydroxyethyl ((benzyloxy)carbonyl)-L-tryptophanate (CAS 642478-72-6), a certified reference material (molecular formula C21H22N2O5, MW 382.41 g/mol) for analytical method development and quality control.

Structurally, 2-hydroxyethyl ((benzyloxy)carbonyl)-L-tryptophanate (C21H22N2O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 382.41 g/mol, it falls into the moderately-high-molecular-weight range. 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).

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), 2-hydroxyethyl ((benzyloxy)carbonyl)-L-tryptophanate 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.
