Chemical Structure

Methyl 6-amino-4-(3-bromophenyl)-5-cyano-2-[({3-cyano-5H,6H,7H,8H,9H-cyclohepta[b]pyridin-2-yl}sulfanyl)methyl]-4H-pyran-3-carboxylate CAS 354556-65-3 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 Methyl 6-amino-4-(3-bromophenyl)-5-cyano-2-[({3-cyano-5H,6H,7H,8H,9H-cyclohepta[b]pyridin-2-yl}sulfanyl)methyl]-4H-pyran-3-carboxylate (CAS 354556-65-3), a certified reference material (molecular formula C26H23BrN4O3S, MW 551.45 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, bromine substitution, Methyl 6-amino-4-(3-bromophenyl)-5-cyano-2-[({3-cyano-5H,6H,7H,8H,9H-cyclohepta[b]pyridin-2-yl}sulfanyl)methyl]-4H-pyran-3-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 551.45 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.
