Chemical Structure

(1R,5R,6S)-Ethyl 5-Acetoxy-7-oxabicyclo[4.1.0]hept-2-ene-3-carboxylate CAS 347378-69-2 chemical structure

Description

The occurrence of (1R,5R,6S)-Ethyl 5-Acetoxy-7-oxabicyclo[4.1.0]hept-2-ene-3-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.

(1R,5R,6S)-Ethyl 5-Acetoxy-7-oxabicyclo[4.1.0]hept-2-ene-3-carboxylate (CAS 347378-69-2), molecular formula C11H14O5 and molecular weight 226.23 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, (1R,5R,6S)-Ethyl 5-Acetoxy-7-oxabicyclo[4.1.0]hept-2-ene-3-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 226.23 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
