Chemical Structure
Description
(2-Bromo-5-methylphenyl)hydrazine hydrochloride (C7H9BrN2HCl) contains a nitrile group, chlorine/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.
(2-Bromo-5-methylphenyl)hydrazine hydrochloride (CAS 60481-41-6), molecular formula C7H9BrN2HCl and molecular weight 237.53 g/mol, is a CATO reference standard with documented purity and traceability.
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.
As a certified reference material (CRM), (2-Bromo-5-methylphenyl)hydrazine hydrochloride 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.
