Chemical Structure
Description
CATO supplies 5,6-Dichlorobenzo[c]isoxazole (CAS 14367-17-0), a certified reference material (molecular formula C7H3Cl2NO, MW 188.01 g/mol) for analytical method development and quality control.
Structurally, 5,6-Dichlorobenzo[c]isoxazole (C7H3Cl2NO) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 188.01 g/mol, it falls into the medium-molecular-weight range. 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.
