Chemical Structure
Description
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, S-acetyl-PEG2-Boc is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 292.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
S-acetyl-PEG2-Boc (CAS 1820641-93-7) is a high-purity analytical reference standard with the molecular formula C13H24O5S and a molecular weight of 292.39 g/mol.
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.
