Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 201.20 g/mol gives 4,7-Difluoro-2-hydrazinylbenzo[d]thiazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4,7-Difluoro-2-hydrazinylbenzo[d]thiazole (CAS 1177330-16-3), molecular formula C7H5F2N3S and molecular weight 201.20 g/mol, is a CATO reference standard with documented purity and traceability.
4,7-Difluoro-2-hydrazinylbenzo[d]thiazole (C7H5F2N3S) contains a nitrile group, sulfur-containing functionality, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
