Chemical Structure
Description
The occurrence of 2,3-Dimethoxybenzylzinc chloride is closely related to a salt form, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2,3-Dimethoxybenzylzinc chloride (CAS 737797-22-7), molecular formula C9H11ClO2Zn and molecular weight 252.04 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2,3-Dimethoxybenzylzinc chloride (C9H11ClO2Zn) contains a salt form, a carboxylic acid group, a hydroxyl group, an ether linkage, 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 252.04 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
