Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 203.07 g/mol gives 4-(2-Chloroethyl)benzoyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-(2-Chloroethyl)benzoyl chloride (CAS 7623-03-2) is a high-purity analytical reference standard with the molecular formula C9H8Cl2O and a molecular weight of 203.07 g/mol.
4-(2-Chloroethyl)benzoyl chloride (C9H8Cl2O) contains a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
