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.
CATO supplies 875770-34-6 Azido-PEG3-biotin conjugate MFCD20134145 11-[(R)-(+)-Biotinylamino]-1-azido-3,6,9-trioxaundecane (CAS 875770-34-6), a certified reference material (molecular formula C18H32N6O5S, MW 444.55 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 875770-34-6 Azido-PEG3-biotin conjugate MFCD20134145 11-[(R)-(+)-Biotinylamino]-1-azido-3,6,9-trioxaundecane is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 444.55 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.
