Chemical Structure
Description
CATO supplies m-PEG15-acetic acid (CAS 2417256-16-5), a certified reference material (molecular formula C33H66O18, MW 750.87 g/mol) for analytical method development and quality control.
m-PEG15-acetic acid (C33H66O18) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.
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.
