Chemical Structure
Description
The occurrence of Azido-PEG5-CH2CO2-PFP is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Azido-PEG5-CH2CO2-PFP (CAS 2144777-92-2), molecular formula C18H22F5N3O7 and molecular weight 487.38 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Azido-PEG5-CH2CO2-PFP (C18H22F5N3O7) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Azido-PEG5-CH2CO2-PFP 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.
