Chemical Structure

EZ-Link NHS-PEG12-Biotin CAS 365441-71-0 chemical structure

Description

CATO supplies EZ-Link NHS-PEG12-Biotin (CAS 365441-71-0), a certified reference material (molecular formula C41H72N4O18S, MW 941.09 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, EZ-Link NHS-PEG12-Biotin is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 941.09 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
