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.
3,4-Dichloro-2-(thiomethyl)benzophenone (CAS 951888-27-0) is a high-purity analytical reference standard with the molecular formula C14H10Cl2OS and a molecular weight of 297.20 g/mol.
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system, 3,4-Dichloro-2-(thiomethyl)benzophenone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 297.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
