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 Enrofloxacin D5 hydrochloride.
CATO supplies Enrofloxacin D5 hydrochloride (CAS 2733718-29-9), a certified reference material (molecular formula C19H17D5FN3O3HCl, MW 400.89 g/mol) for analytical method development and quality control.
Based on its molecular formula C19H17D5FN3O3HCl, Enrofloxacin D5 hydrochloride contains deuterium isotope labeling, a steroid core, 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 400.89 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.
