Chemical Structure
Description
Methyl 2-chloro-5-hydrazinobenzoate hydrochloride (CAS 723242-88-4) is a high-purity analytical reference standard with the molecular formula C8H9ClN2O2HCl and a molecular weight of 237.08 g/mol.
Based on its molecular formula C8H9ClN2O2HCl, Methyl 2-chloro-5-hydrazinobenzoate hydrochloride contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 237.08 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), Methyl 2-chloro-5-hydrazinobenzoate 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.
