Chemical Structure
Description
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.
4-(Benzyloxy)-4'-(methylsulfanyl)[1,1'-biphenyl]-3-carbaldehyde (CAS 893735-66-5) is a high-purity analytical reference standard with the molecular formula C21H18O2S and a molecular weight of 334.43 g/mol.
The molecular framework of 4-(Benzyloxy)-4'-(methylsulfanyl)[1,1'-biphenyl]-3-carbaldehyde (C21H18O2S) is characterized by a steroid core, a sulfone group, a hydroxyl group, an ether linkage. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
