Chemical Structure
Description
CATO supplies 2-Chlorophenylhydrazine Hydrochloride (CAS 41052-75-9), a certified reference material (molecular formula C6H7ClN2HCl, MW 179.04 g/mol) for analytical method development and quality control.
2-Chlorophenylhydrazine Hydrochloride (C6H7ClN2HCl) contains a nitrile group, chlorine 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.
