Chemical Structure
Description
CATO supplies dPEG<SUP>®</SUP><SUB>8</SUB>-SATA (S-acetyl-dPEG<SUP>®</SUP><SUB>8</SUB>-NHS ester) (CAS 1070798-99-0), a certified reference material (molecular formula C25H43NO13S, MW 597.67 g/mol) for analytical method development and quality control.
dPEG<SUP>®</SUP><SUB>8</SUB>-SATA (S-acetyl-dPEG<SUP>®</SUP><SUB>8</SUB>-NHS ester) (C25H43NO13S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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. 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.
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.
