Chemical Structure
Description
The occurrence of 4-Methylbenzyl bromide is closely related to bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Methylbenzyl bromide (CAS 104-81-4), molecular formula C8H15Br and molecular weight 191.11 g/mol, is a CATO reference standard with documented purity and traceability.
4-Methylbenzyl bromide (C8H15Br) contains bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures 4-Methylbenzyl bromide 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.
