Chemical Structure

2-(3-Methylchromeno[4,3-c]pyrazol-1(4H)-yl)aniline CAS 654650-99-4 chemical structure

Description

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

CATO supplies 2-(3-Methylchromeno[4,3-c]pyrazol-1(4H)-yl)aniline (CAS 654650-99-4), a certified reference material (molecular formula C17H15N3O, MW 277.32 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 2-(3-Methylchromeno[4,3-c]pyrazol-1(4H)-yl)aniline is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 277.32 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.

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.
