Compared with other compounds in its class, the molecular weight of 278.18 g/mol gives [4-(Tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]thiourea distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
[4-(Tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]thiourea (CAS 2249914-86-9) is a high-purity analytical reference standard with the molecular formula C13H19BN2O2S and a molecular weight of 278.18 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, [4-(Tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]thiourea is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 278.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
