Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 168.19 g/mol gives 2-amino-5-fluorobenzothiazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-amino-5-fluorobenzothiazole (CAS 20358-07-0), a certified reference material (molecular formula C7H5FN2S, MW 168.19 g/mol) for analytical method development and quality control.
Structurally, 2-amino-5-fluorobenzothiazole (C7H5FN2S) contains a nitrile group, sulfur-containing functionality, fluorine 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 168.19 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
