The occurrence of 1-Phenylbut-3-yn-2-one is closely related to a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-Phenylbut-3-yn-2-one (CAS 31739-46-5), molecular formula C10H8O and molecular weight 144.17 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-Phenylbut-3-yn-2-one (C10H8O) contains a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 144.17 g/mol, it falls into the low-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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 1-Phenylbut-3-yn-2-one 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.
