Chemical Structure
Description
The occurrence of 4-bromo-3,5-dimethyl-pyridine is closely related to bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-bromo-3,5-dimethyl-pyridine (CAS 201286-65-9), molecular formula C7H14BrN and molecular weight 192.10 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-bromo-3,5-dimethyl-pyridine (C7H14BrN) is characterized by bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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), 4-bromo-3,5-dimethyl-pyridine 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.
