Chemical Structure

Bis-PEG25-acid CAS 2567200-14-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 1219.40 g/mol gives Bis-PEG25-acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Bis-PEG25-acid (CAS 2567200-14-8) is a high-purity analytical reference standard with the molecular formula C54H106O29 and a molecular weight of 1219.40 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Bis-PEG25-acid is typically white to off-white amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1219.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
