tert-Butyldiphenylmethanol CAS 1657-60-9 chemical structure

Description

tert-Butyldiphenylmethanol (CAS 1657-60-9) is a high-purity analytical reference standard with the molecular formula C17H20O and a molecular weight of 240.34 g/mol.

Structurally, tert-Butyldiphenylmethanol (C17H20O) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 240.34 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
