Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 182.60 g/mol gives (5-Chlorobenzofuran-3-yl)methanol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(5-Chlorobenzofuran-3-yl)methanol (CAS 650616-58-3), molecular formula C9H7ClO2 and molecular weight 182.60 g/mol, is a CATO reference standard with documented purity and traceability.
(5-Chlorobenzofuran-3-yl)methanol (C9H7ClO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 (5-Chlorobenzofuran-3-yl)methanol 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.
