Chemical Structure
Description
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.
3,5-Dichlorobenzylzinc chloride 0.5 M in Tetrahydrofuran (CAS 352530-34-8), molecular formula C7H5Cl3Zn and molecular weight 260.88 g/mol, is a CATO reference standard with documented purity and traceability.
3,5-Dichlorobenzylzinc chloride 0.5 M in Tetrahydrofuran (C7H5Cl3Zn) contains a salt form, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
