Chemical Structure
Description
The occurrence of 2,5-Dimethylbenzylzinc chloride is closely related to a salt form, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2,5-Dimethylbenzylzinc chloride (CAS 737797-24-9), molecular formula C9H11ClZn and molecular weight 220.05 g/mol, is a CATO reference standard with documented purity and traceability.
2,5-Dimethylbenzylzinc chloride (C9H11ClZn) 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. 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.
