Chemical Structure

Neomycin B CAS 119-04-0 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 Neomycin B (CAS 119-04-0), a certified reference material (molecular formula C23H46N6O13, MW 614.64 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Neomycin B is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 614.64 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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