N3-PEG2-C2-NHS ester CAS 1312309-64-0 chemical structure

Description

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

CATO supplies N3-PEG2-C2-NHS ester (CAS 1312309-64-0), a certified reference material (molecular formula C11H16N4O6, MW 300.27 g/mol) for analytical method development and quality control.

N3-PEG2-C2-NHS ester (C11H16N4O6) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO manufactures N3-PEG2-C2-NHS ester 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.
