4-[(E)-2-[(4-Bromophenyl)methylidene]hydrazin-1-yl]quinazoline CAS 129177-05-5

Description

Compared with other compounds in its class, the molecular weight of 327.18 g/mol gives 4-[(E)-2-[(4-Bromophenyl)methylidene]hydrazin-1-yl]quinazoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-[(E)-2-[(4-Bromophenyl)methylidene]hydrazin-1-yl]quinazoline (CAS 129177-05-5), molecular formula C15H11BrN4 and molecular weight 327.18 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution, 4-[(E)-2-[(4-Bromophenyl)methylidene]hydrazin-1-yl]quinazoline is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 327.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
