Chemical Structure

Ethyl (1R,1aR,6bS)-5-hydroxy-1a,6b-dihydro-1H-cyclopropa[b]benzofuran-1-carboxylate CAS 1446091-39-9 chemical structure

Description

The occurrence of Ethyl (1R,1aR,6bS)-5-hydroxy-1a,6b-dihydro-1H-cyclopropa[b]benzofuran-1-carboxylate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ethyl (1R,1aR,6bS)-5-hydroxy-1a,6b-dihydro-1H-cyclopropa[b]benzofuran-1-carboxylate (CAS 1446091-39-9), molecular formula C12H12O4 and molecular weight 220.22 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Ethyl (1R,1aR,6bS)-5-hydroxy-1a,6b-dihydro-1H-cyclopropa[b]benzofuran-1-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 220.22 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 Ethyl (1R,1aR,6bS)-5-hydroxy-1a,6b-dihydro-1H-cyclopropa[b]benzofuran-1-carboxylate 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.
