Chemical Structure
Description
CATO manufactures Azido-PEG7-CH2COOH 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.
Azido-PEG7-CH2COOH (CAS 1446411-32-0), molecular formula C16H31N3O9 and molecular weight 409.43 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Azido-PEG7-CH2COOH (C16H31N3O9) is characterized by an amide 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. 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.
