Chemical Structure
Description
The occurrence of Ethyl 3-(5-chlorobenzofuran-2-yl)benzoate is closely related to a steroid core, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Ethyl 3-(5-chlorobenzofuran-2-yl)benzoate (CAS 835595-15-8), molecular formula C17H13ClO3 and molecular weight 300.74 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Ethyl 3-(5-chlorobenzofuran-2-yl)benzoate (C17H13ClO3) contains a steroid core, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 300.74 g/mol, it falls into the moderately-high-molecular-weight range. 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.
CATO manufactures Ethyl 3-(5-chlorobenzofuran-2-yl)benzoate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
