Chemical Structure

3-Chloro-5,6-dihydro-4H-cyclopenta[c]isoxazole CAS 1333495-30-9 chemical structure

Description

The occurrence of 3-Chloro-5,6-dihydro-4H-cyclopenta[c]isoxazole is closely related to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3-Chloro-5,6-dihydro-4H-cyclopenta[c]isoxazole (CAS 1333495-30-9), a certified reference material (molecular formula C6H6ClNO, MW 143.57 g/mol) for analytical method development and quality control.

Based on its molecular formula C6H6ClNO, 3-Chloro-5,6-dihydro-4H-cyclopenta[c]isoxazole contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 143.57 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), 3-Chloro-5,6-dihydro-4H-cyclopenta[c]isoxazole meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
