Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 162.19 g/mol gives 4-(2-Propyn-1-yloxy)benzenemethanol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-(2-Propyn-1-yloxy)benzenemethanol (CAS 34905-02-7) is a high-purity analytical reference standard with the molecular formula C10H10O2 and a molecular weight of 162.19 g/mol.
The molecular framework of 4-(2-Propyn-1-yloxy)benzenemethanol (C10H10O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 4-(2-Propyn-1-yloxy)benzenemethanol 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.
