Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(2,3-Dichlorophenyl)ethan-1-ol.
1-(2,3-Dichlorophenyl)ethan-1-ol (CAS 54798-91-3), molecular formula C8H8Cl2O and molecular weight 191.05 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C8H8Cl2O, 1-(2,3-Dichlorophenyl)ethan-1-ol contains a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 191.05 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.
