Description
As a certified reference material (CRM), 2-([1,1':3',1''-Terphenyl]-3-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane 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.
2-([1,1':3',1''-Terphenyl]-3-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 1115023-84-1) is a high-purity analytical reference standard with the molecular formula C24H25BO2 and a molecular weight of 356.27 g/mol.
Structurally, 2-([1,1':3',1''-Terphenyl]-3-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (C24H25BO2) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.5, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 356.27 g/mol, it falls into the moderately-high-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.
