Chemical Structure
Description
The occurrence of 3-bromo-1,5-dimethyl-pyrazole;trifluoromethanesulfonic acid is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-bromo-1,5-dimethyl-pyrazole;trifluoromethanesulfonic acid (CAS 1669415-87-5), molecular formula C5H11BrN2CHF3O3S and molecular weight 329.13 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-bromo-1,5-dimethyl-pyrazole;trifluoromethanesulfonic acid (C5H11BrN2CHF3O3S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/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.
CATO manufactures 3-bromo-1,5-dimethyl-pyrazole;trifluoromethanesulfonic acid 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.
