Chemical Structure

tert-Butyl (E)-2-(1-(3,5-dibromothiophen-2-yl)ethylidene)hydrazine-1-carboxylate CAS 864774-20-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 398.11 g/mol gives tert-Butyl (E)-2-(1-(3,5-dibromothiophen-2-yl)ethylidene)hydrazine-1-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies tert-Butyl (E)-2-(1-(3,5-dibromothiophen-2-yl)ethylidene)hydrazine-1-carboxylate (CAS 864774-20-9), a certified reference material (molecular formula C11H14Br2N2O2S, MW 398.11 g/mol) for analytical method development and quality control.

The molecular framework of tert-Butyl (E)-2-(1-(3,5-dibromothiophen-2-yl)ethylidene)hydrazine-1-carboxylate (C11H14Br2N2O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
