Chemical Structure

EthyleneOxide CAS 75-21-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 44.05 g/mol gives EthyleneOxide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies EthyleneOxide (CAS 75-21-8), a certified reference material (molecular formula C2H4O, MW 44.05 g/mol) for analytical method development and quality control.

Structurally, EthyleneOxide (C2H4O) contains a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 44.05 g/mol, it falls into the low-molecular-weight range.

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), EthyleneOxide 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.
