Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Azido-dPEG <SUP>®</SUP><SUB>4</SUB>-TFP ester.
CATO supplies Azido-dPEG <SUP>®</SUP><SUB>4</SUB>-TFP ester (CAS 1807505-33-4), a certified reference material (molecular formula C17H21F4N3O6, MW 439.36 g/mol) for analytical method development and quality control.
Structurally, Azido-dPEG <SUP>®</SUP><SUB>4</SUB>-TFP ester (C17H21F4N3O6) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 439.36 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
