Chemical Structure

oxetane-3-carbonyl chloride CAS 1637758-08-7 chemical structure

Description

As a certified reference material (CRM), oxetane-3-carbonyl chloride 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.

oxetane-3-carbonyl chloride (CAS 1637758-08-7) is a high-purity analytical reference standard with the molecular formula C4H5ClO2 and a molecular weight of 120.53 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, oxetane-3-carbonyl chloride is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 120.53 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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