Chemical Structure

1,4-Bis(benzyloxy)but-2-ene CAS 68972-96-3 chemical structure

Description

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

1,4-Bis(benzyloxy)but-2-ene (CAS 68972-96-3), molecular formula C18H20O2 and molecular weight 268.35 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1,4-Bis(benzyloxy)but-2-ene (C18H20O2) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 268.35 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

As a certified reference material (CRM), 1,4-Bis(benzyloxy)but-2-ene 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.
