Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(4-Chloro-2,5-difluorobenzoyl)piperidine-4-carbohydrazide.
1-(4-Chloro-2,5-difluorobenzoyl)piperidine-4-carbohydrazide (CAS 388094-06-2), molecular formula C13H14ClF2N3O2 and molecular weight 317.72 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C13H14ClF2N3O2, 1-(4-Chloro-2,5-difluorobenzoyl)piperidine-4-carbohydrazide contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 317.72 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
