Chemical Structure
Description
(R)-Diclofop (CAS 71283-28-8) is a high-purity analytical reference standard with the molecular formula C15H12Cl2O4 and a molecular weight of 327.16 g/mol.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution, (R)-Diclofop is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 327.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
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 (R)-Diclofop 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.
