Chemical Structure
Description
As a certified reference material (CRM), 4-(4-Chloro-2-methylphenoxy)butanehydrazide 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.
4-(4-Chloro-2-methylphenoxy)butanehydrazide (CAS 545355-20-2) is a high-purity analytical reference standard with the molecular formula C11H15ClN2O2 and a molecular weight of 242.70 g/mol.
Structurally, 4-(4-Chloro-2-methylphenoxy)butanehydrazide (C11H15ClN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 242.70 g/mol, it falls into the medium-molecular-weight range. 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.
