Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Chloro-6-fluorobenzylzinc chloride.
CATO supplies 2-Chloro-6-fluorobenzylzinc chloride (CAS 307531-98-2), a certified reference material (molecular formula C7H5Cl2FZn, MW 244.43 g/mol) for analytical method development and quality control.
Structurally, 2-Chloro-6-fluorobenzylzinc chloride (C7H5Cl2FZn) contains a salt form, 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 244.43 g/mol, it falls into the medium-molecular-weight range. 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.
