Chemical Structure
Description
2-Ethynyl-4'-methoxy-1,1'-biphenyl (CAS 911204-92-7), molecular formula C15H12O and molecular weight 208.26 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-Ethynyl-4'-methoxy-1,1'-biphenyl (C15H12O) contains a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 208.26 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.
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), 2-Ethynyl-4'-methoxy-1,1'-biphenyl 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.
