Chemical Structure

Propargyl-PEG2-Boc CAS 1807503-80-5 chemical structure

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Propargyl-PEG2-Boc is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 228.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

CATO supplies Propargyl-PEG2-Boc (CAS 1807503-80-5), a certified reference material (molecular formula C12H20O4, MW 228.28 g/mol) for analytical method development and quality control.

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.
