Chemical Structure
Description
1,2-Difluoro-4-(2-methylallyl)benzene (CAS 951892-66-3) is a high-purity analytical reference standard with the molecular formula C10H10F2 and a molecular weight of 168.18 g/mol.
Structurally, 1,2-Difluoro-4-(2-methylallyl)benzene (C10H10F2) contains fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 168.18 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
