Chemical Structure
Description
As a certified reference material (CRM), [trans-2-ethynylcyclopropyl]benzene 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.
[trans-2-ethynylcyclopropyl]benzene (CAS 144293-48-1), molecular formula C11H16 and molecular weight 148.24 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an aromatic ring system, [trans-2-ethynylcyclopropyl]benzene is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 148.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
