(1S,2R,3S)-4-(3-Cyano-5-fluorophenoxy)-2-fluoro-3-hydroxy-7-(methylsulfonyl)-2,3-dihydro-1H-inden-1-yl acetate CAS 1672668-28-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (1S,2R,3S)-4-(3-Cyano-5-fluorophenoxy)-2-fluoro-3-hydroxy-7-(methylsulfonyl)-2,3-dihydro-1H-inden-1-yl acetate.

CATO supplies (1S,2R,3S)-4-(3-Cyano-5-fluorophenoxy)-2-fluoro-3-hydroxy-7-(methylsulfonyl)-2,3-dihydro-1H-inden-1-yl acetate (CAS 1672668-28-8), a certified reference material (molecular formula C19H15F2NO6S, MW 423.39 g/mol) for analytical method development and quality control.

Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, (1S,2R,3S)-4-(3-Cyano-5-fluorophenoxy)-2-fluoro-3-hydroxy-7-(methylsulfonyl)-2,3-dihydro-1H-inden-1-yl acetate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 423.39 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.

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.
