(1<I>R</I>,5<I>S</I>)-3-oxabicyclo[3.3.0]oct-6-en-2-one CAS 128946-78-1 chemical structure

Description

CATO manufactures (1<I>R</I>,5<I>S</I>)-3-oxabicyclo[3.3.0]oct-6-en-2-one 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.

CATO supplies (1<I>R</I>,5<I>S</I>)-3-oxabicyclo[3.3.0]oct-6-en-2-one (CAS 128946-78-1), a certified reference material (molecular formula C7H8O2, MW 124.14 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, (1<I>R</I>,5<I>S</I>)-3-oxabicyclo[3.3.0]oct-6-en-2-one is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 124.14 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.
