Chemical Structure
Description
4-Bromo-1-n-cyclopropylbenzene-1,2-diamine (CAS 1092291-41-2), molecular formula C9H11BrN2 and molecular weight 227.10 g/mol, is a CATO reference standard with documented purity and traceability.
4-Bromo-1-n-cyclopropylbenzene-1,2-diamine (C9H11BrN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
