Chemical Structure
Description
The occurrence of 2,5-Difluorobenzylzinc chloride 0.5 M in Tetrahydrofuran is closely related to a salt form, fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2,5-Difluorobenzylzinc chloride 0.5 M in Tetrahydrofuran (CAS 312692-89-0), molecular formula C7H5ClF2Zn and molecular weight 227.97 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a salt form, fluorine/chlorine substitution, an aromatic ring system, 2,5-Difluorobenzylzinc chloride 0.5 M in Tetrahydrofuran is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 227.97 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).
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.
