Description
M5E1132G4W 676-58-4 Methylmagnesium chloride Magnesium, chloromethyl- Chloromethylmagnesium EINECS 211-629-7 HSDB 5740 UNII-M5E1132G4W EC 211-629-7 (CAS 676-58-4) is a high-purity analytical reference standard with the molecular formula CH3ClMg and a molecular weight of 74.79 g/mol.
The molecular framework of M5E1132G4W 676-58-4 Methylmagnesium chloride Magnesium, chloromethyl- Chloromethylmagnesium EINECS 211-629-7 HSDB 5740 UNII-M5E1132G4W EC 211-629-7 (CH3ClMg) is characterized by a salt form, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
As a certified reference material (CRM), M5E1132G4W 676-58-4 Methylmagnesium chloride Magnesium, chloromethyl- Chloromethylmagnesium EINECS 211-629-7 HSDB 5740 UNII-M5E1132G4W EC 211-629-7 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
