Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (3Z)-3-{[5-(3-chlorophenyl)furan-2-yl]methylidene}-1,3-dihydro-2-benzofuran-1-one 338786-06-4 6F-033.

(3Z)-3-{[5-(3-chlorophenyl)furan-2-yl]methylidene}-1,3-dihydro-2-benzofuran-1-one 338786-06-4 6F-033 (CAS 338786-06-4) is a high-purity analytical reference standard with the molecular formula C19H11ClO3 and a molecular weight of 322.74 g/mol.

(3Z)-3-{[5-(3-chlorophenyl)furan-2-yl]methylidene}-1,3-dihydro-2-benzofuran-1-one 338786-06-4 6F-033 (C19H11ClO3) contains a steroid core, 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.
