Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 6,7-Dichloro-3-oxabicyclo[3.2.0]heptane-2,4-dione (CAS 89361-81-9), a certified reference material (molecular formula C6H4Cl2O3, MW 195.00 g/mol) for analytical method development and quality control.
Structurally, 6,7-Dichloro-3-oxabicyclo[3.2.0]heptane-2,4-dione (C6H4Cl2O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 195.00 g/mol, it falls into the medium-molecular-weight range. 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).
CATO manufactures 6,7-Dichloro-3-oxabicyclo[3.2.0]heptane-2,4-dione 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.
