Chemical Structure

Boc-Glu(OtBu)-OSu CAS 32886-55-8 chemical structure

Description

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.

CATO supplies Boc-Glu(OtBu)-OSu (CAS 32886-55-8), a certified reference material (molecular formula C18H28N2O8, MW 400.42 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Boc-Glu(OtBu)-OSu is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 400.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

CATO manufactures Boc-Glu(OtBu)-OSu under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
