1-(thiophen-2-ylmethyl)-1h-pyrazol-4-boronic acid pinacol ester 1-(thiophen-2-ylmethyl)-1h-pyrazole-4-boronic acid, pinacol ester 1-(thiophen-2-ylmethyl)pyrazole-4-boronic acid, pinacol ester 1-[(2-thienyl)methyl]-1h-pyrazole-4-boronic acid pinacol ester, 97% 4-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-1-(2-thienylmethyl)-1H-pyrazole 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1-(thiophen-2-ylmethyl)-1h-pyraz 4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-1-thiophen-2-ylmethyl-1h-pyrazole 864754-19-8 (CAS 864754-19-8) is a high-purity analytical reference standard with the molecular formula C14H27BN2O2S and a molecular weight of 298.25 g/mol.
Structurally, 1-(thiophen-2-ylmethyl)-1h-pyrazol-4-boronic acid pinacol ester 1-(thiophen-2-ylmethyl)-1h-pyrazole-4-boronic acid, pinacol ester 1-(thiophen-2-ylmethyl)pyrazole-4-boronic acid, pinacol ester 1-[(2-thienyl)methyl]-1h-pyrazole-4-boronic acid pinacol ester, 97% 4-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-1-(2-thienylmethyl)-1H-pyrazole 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1-(thiophen-2-ylmethyl)-1h-pyraz 4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-1-thiophen-2-ylmethyl-1h-pyrazole 864754-19-8 (C14H27BN2O2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.5, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 298.25 g/mol, it falls into the medium-molecular-weight range. 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.
