Methyl 2-(1,1-dichloro-4-oxo-1,1a,2,3,4,8b-hexahydrobenzo[a]cyclopropa[c][7]annulen-3-yl)-2-oxoacetate CAS 2055840-43-0

Description

Methyl 2-(1,1-dichloro-4-oxo-1,1a,2,3,4,8b-hexahydrobenzo[a]cyclopropa[c][7]annulen-3-yl)-2-oxoacetate (CAS 2055840-43-0), molecular formula C15H12Cl2O4 and molecular weight 327.16 g/mol, is a CATO reference standard with documented purity and traceability.

Methyl 2-(1,1-dichloro-4-oxo-1,1a,2,3,4,8b-hexahydrobenzo[a]cyclopropa[c][7]annulen-3-yl)-2-oxoacetate (C15H12Cl2O4) contains a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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 Methyl 2-(1,1-dichloro-4-oxo-1,1a,2,3,4,8b-hexahydrobenzo[a]cyclopropa[c][7]annulen-3-yl)-2-oxoacetate 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.
