Chemical Structure

Aminooxy-PEG7-methane CAS 1370698-27-3 chemical structure

Description

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.

Aminooxy-PEG7-methane (CAS 1370698-27-3), molecular formula C15H33NO8 and molecular weight 355.42 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, Aminooxy-PEG7-methane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 355.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
