Chemical Structure

1-(2,5-Difluoropyridin-4-yl)ethanol CAS 1784520-98-4 chemical structure

Description

The occurrence of 1-(2,5-Difluoropyridin-4-yl)ethanol is closely related to an amide group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 1-(2,5-Difluoropyridin-4-yl)ethanol (CAS 1784520-98-4), a certified reference material (molecular formula C7H7F2NO, MW 159.13 g/mol) for analytical method development and quality control.

Structurally, 1-(2,5-Difluoropyridin-4-yl)ethanol (C7H7F2NO) contains an amide group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 159.13 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
