Chemical Structure

7-Chloro-1-methoxydibenzo[b,d]furan-4-carbonitrile CAS 1956366-41-8 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 7-Chloro-1-methoxydibenzo[b,d]furan-4-carbonitrile.

CATO supplies 7-Chloro-1-methoxydibenzo[b,d]furan-4-carbonitrile (CAS 1956366-41-8), a certified reference material (molecular formula C14H8ClNO2, MW 257.67 g/mol) for analytical method development and quality control.

7-Chloro-1-methoxydibenzo[b,d]furan-4-carbonitrile (C14H8ClNO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
