Chemical Structure

m-PEG5-NH2 CAS 5498-83-9 chemical structure

Description

m-PEG5-NH2 (CAS 5498-83-9), molecular formula C11H25NO5 and molecular weight 251.32 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, m-PEG5-NH2 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 251.32 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.

CATO manufactures m-PEG5-NH2 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
