Chemical Structure
Description
6-Methyl-5-((3-(2-(methylthio)pyrimidin-4-yl)pyridin-2-yl)oxy)naphthalen-1-amine (CAS 2245062-49-9) is a high-purity analytical reference standard with the molecular formula C21H18N4OS and a molecular weight of 374.46 g/mol.
Structurally, 6-Methyl-5-((3-(2-(methylthio)pyrimidin-4-yl)pyridin-2-yl)oxy)naphthalen-1-amine (C21H18N4OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 374.46 g/mol, it falls into the moderately-high-molecular-weight range. 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.
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.
