Chemical Structure
Description
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.
CATO supplies N-((2-Chlorobenzoyl)oxy)-2-(quinolin-8-yloxy)acetimidamide (CAS 88758-18-3), a certified reference material (molecular formula C18H14ClN3O3, MW 355.78 g/mol) for analytical method development and quality control.
Structurally, N-((2-Chlorobenzoyl)oxy)-2-(quinolin-8-yloxy)acetimidamide (C18H14ClN3O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 355.78 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
