Description
CATO manufactures Azido-PEG3-Sulfone-PEG4-Boc 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.
CATO supplies Azido-PEG3-Sulfone-PEG4-Boc (CAS 2055023-76-0), a certified reference material (molecular formula C23H45N3O11S, MW 571.68 g/mol) for analytical method development and quality control.
The molecular framework of Azido-PEG3-Sulfone-PEG4-Boc (C23H45N3O11S) is characterized by an amide group, a sulfone group, a carboxylic acid 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
