4,4-Difluoro-1,3-dimethyl-4-bora-3a,4a-diaza-s-indacene CAS 154793-49-4

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.

4,4-Difluoro-1,3-dimethyl-4-bora-3a,4a-diaza-s-indacene (CAS 154793-49-4), molecular formula C11H11BF2N2 and molecular weight 220.03 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution, 4,4-Difluoro-1,3-dimethyl-4-bora-3a,4a-diaza-s-indacene is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 220.03 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
