Description
CATO manufactures 3-Chloro-4-(dichloromethyl)-2(5H)-furanone 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.
3-Chloro-4-(dichloromethyl)-2(5H)-furanone (CAS 122551-89-7) is a high-purity analytical reference standard with the molecular formula C5H3Cl3O2 and a molecular weight of 201.44 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 3-Chloro-4-(dichloromethyl)-2(5H)-furanone is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 201.44 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.
