Chemical Structure
Description
The molecular framework of Hydroxy-PEG5-C2-methyl ester (C14H28O8) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.
CATO supplies Hydroxy-PEG5-C2-methyl ester (CAS 2100306-80-5), a certified reference material (molecular formula C14H28O8, MW 324.37 g/mol) for analytical method development and quality control.
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.
