Chemical Structure

I-PEG5-OH CAS 1883516-31-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 348.18 g/mol gives I-PEG5-OH distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

I-PEG5-OH (CAS 1883516-31-1) is a high-purity analytical reference standard with the molecular formula C10H21IO5 and a molecular weight of 348.18 g/mol.

I-PEG5-OH (C10H21IO5) contains a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
