Chemical Structure

5-Oxabicyclo[2.1.0]pentane CAS 185-96-6 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Oxabicyclo[2.1.0]pentane.

5-Oxabicyclo[2.1.0]pentane (CAS 185-96-6), molecular formula C4H6O and molecular weight 70.09 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-Oxabicyclo[2.1.0]pentane (C4H6O) is characterized by a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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), 5-Oxabicyclo[2.1.0]pentane 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.
