Chemical Structure
Description
3,5-Dibromo-4-methyl-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-pyrazole (CAS 2771081-10-6), molecular formula C10H18Br2N2OSi and molecular weight 370.16 g/mol, is a CATO reference standard with documented purity and traceability.
3,5-Dibromo-4-methyl-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-pyrazole (C10H18Br2N2OSi) contains an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 3,5-Dibromo-4-methyl-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-pyrazole 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.
