Description
As a certified reference material (CRM), 4-Bromo-5-ethyl-3-methyl-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-pyrazole 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.
4-Bromo-5-ethyl-3-methyl-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-pyrazole (CAS 2755144-50-2) is a high-purity analytical reference standard with the molecular formula C12H23BrN2OSi and a molecular weight of 319.31 g/mol.
Structurally, 4-Bromo-5-ethyl-3-methyl-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-pyrazole (C12H23BrN2OSi) contains an amide group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 319.31 g/mol, it falls into the moderately-high-molecular-weight range. 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.
