Chemical Structure
Description
5-Chloro-2-methoxyphenylmagnesium bromide, 0.50 M in THF (CAS 419535-75-4), molecular formula C7H6ClOBrMg and molecular weight 245.78 g/mol, is a CATO reference standard with documented purity and traceability.
5-Chloro-2-methoxyphenylmagnesium bromide, 0.50 M in THF (C7H6ClOBrMg) contains a salt form, a hydroxyl group, an ether linkage, chlorine/bromine 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).
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.
CATO manufactures 5-Chloro-2-methoxyphenylmagnesium bromide, 0.50 M in THF under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
