6'-Amino-4'-ethyl-5'-(4-hydroxyphenyl)-N-methyl-[3,3'-bipyridine]-6-carboxamide CAS 2009273-71-4

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.

6'-Amino-4'-ethyl-5'-(4-hydroxyphenyl)-N-methyl-[3,3'-bipyridine]-6-carboxamide (CAS 2009273-71-4), molecular formula C20H20N4O2 and molecular weight 348.40 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 6'-Amino-4'-ethyl-5'-(4-hydroxyphenyl)-N-methyl-[3,3'-bipyridine]-6-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 348.40 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
