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 Propargyl-PEG4-sulfonic acid.
CATO supplies Propargyl-PEG4-sulfonic acid (CAS 1817735-29-7), a certified reference material (molecular formula C11H20O7S, MW 296.34 g/mol) for analytical method development and quality control.
Propargyl-PEG4-sulfonic acid (C11H20O7S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
