Description
1,3-DIFLUORO-5-ISOTHIOCYANATOBENZENE 3,5-Difluorophenyl isothiocyanate 302912-39-6 AKOS JY2072175 AS00363 TOSLAB 876253 (CAS 302912-39-6) is a high-purity analytical reference standard with the molecular formula C7H3F2NS and a molecular weight of 171.17 g/mol.
Structurally, 1,3-DIFLUORO-5-ISOTHIOCYANATOBENZENE 3,5-Difluorophenyl isothiocyanate 302912-39-6 AKOS JY2072175 AS00363 TOSLAB 876253 (C7H3F2NS) 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 171.17 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.
