Chemical Structure
Description
951891-16-0 4-Bromo-4'-chloro-3'-methylbenzophenone MFCD09801513 (CAS 951891-16-0) is a high-purity analytical reference standard with the molecular formula C14H10BrClO and a molecular weight of 309.59 g/mol.
Owing to a hydroxyl group, an ether linkage, chlorine/bromine substitution, a polycyclic aromatic system, 951891-16-0 4-Bromo-4'-chloro-3'-methylbenzophenone MFCD09801513 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 309.59 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
