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 5-(4-Chlorophenyl)-N-(2-methoxybenzyl)-2-methylfuran-3-carboxamide (CAS 941238-56-8), a certified reference material (molecular formula C20H18ClNO3, MW 355.81 g/mol) for analytical method development and quality control.
Structurally, 5-(4-Chlorophenyl)-N-(2-methoxybenzyl)-2-methylfuran-3-carboxamide (C20H18ClNO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 355.81 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
