Chemical Structure
Description
The occurrence of H-Glu(OBzl)-OBzl · p-tosylate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
H-Glu(OBzl)-OBzl · p-tosylate (CAS 2791-84-6) is a high-purity analytical reference standard with the molecular formula C19H21NO4C7H8O3S and a molecular weight of 499.58 g/mol.
Based on its molecular formula C19H21NO4C7H8O3S, H-Glu(OBzl)-OBzl · p-tosylate contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 499.58 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
CATO manufactures H-Glu(OBzl)-OBzl · p-tosylate 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.
