Chemical Structure
Description
Structurally, 1,3-Dichloro-5-(perfluoroethyl)benzene (C8H3Cl2F5) contains fluorine/chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 265.01 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
1,3-Dichloro-5-(perfluoroethyl)benzene (CAS 1955524-45-4) is a high-purity analytical reference standard with the molecular formula C8H3Cl2F5 and a molecular weight of 265.01 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
