Chemical Structure

Boc-PEG5-methyl ester CAS 1807530-04-6 chemical structure

Description

The occurrence of Boc-PEG5-methyl ester is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Boc-PEG5-methyl ester (CAS 1807530-04-6), a certified reference material (molecular formula C19H36O9, MW 408.48 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Boc-PEG5-methyl ester is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 408.48 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.
