Chemical Structure
Description
The occurrence of 5-((6-Chloropyridin-3-yl)methoxy)-2-cyclopropylbenzofuran-3-carbaldehyde is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 5-((6-Chloropyridin-3-yl)methoxy)-2-cyclopropylbenzofuran-3-carbaldehyde (CAS 1209763-99-4), a certified reference material (molecular formula C18H14ClNO3, MW 327.76 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 5-((6-Chloropyridin-3-yl)methoxy)-2-cyclopropylbenzofuran-3-carbaldehyde is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 327.76 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
