Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-[4-(3,4-Dichlorobenzyloxy)]phenylethyl methanethiosulfonate.
2-[4-(3,4-Dichlorobenzyloxy)]phenylethyl methanethiosulfonate (CAS 887354-40-7) is a high-purity analytical reference standard with the molecular formula C16H16Cl2O3S2 and a molecular weight of 391.33 g/mol.
Based on its molecular formula C16H16Cl2O3S2, 2-[4-(3,4-Dichlorobenzyloxy)]phenylethyl methanethiosulfonate contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 391.33 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
