Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 342.77 g/mol gives (R)-(+)-Coumachlor distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(R)-(+)-Coumachlor (CAS 95271-89-9) is a high-purity analytical reference standard with the molecular formula C19H15ClO4 and a molecular weight of 342.77 g/mol.
The molecular framework of (R)-(+)-Coumachlor (C19H15ClO4) is characterized by a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures (R)-(+)-Coumachlor 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.
