Coumarin Boronic Acid pinacolate ester

Coumarin boronic acid pinacolate ester (CBE) is a more soluble form of coumarin boronic acid (CBA, item no. 14051) that can be used to detect peroxynitrite (Cay-81565), hypochlorous acid, and hydrogen peroxide. Peroxynitrite oxidizes CBE into the fluorescent product 7-hydroxycoumarin (COH), which displays excitation/emission maxima of 332/470 nm, respectively.Formal Name: 7-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2H-1-benzopyran-2-one. CAS Number: 190788-61-5. Synonyms: CBA pinacolate ester, CBE. Molecular Formula: C15H17BO4. Formula Weight: 272.1. Purity: >98%. Emission: 400 nm. Excitation: 332 nm. Formulation: (Request formulation change), A crystalline solid. Solubility: DMF: 11 mg/ml, DMF:PBS(pH 7.2)(1:1): 0.5 mg/ml, DMSO: 3 mg/ml, Ethanol: 1 mg/ml. lambdamax: 280, 320 nm. SMILES: O=C1OC2=CC(B3OC(C)(C)C(C)(C)O3)=CC=C2C=C1. InChi Code: InChI=1S/C15H17BO4/c1-14(2)15(3,4)20-16(19-14)11-7-5-10-6-8-13(17)18-12(10)9-11/h5-9H,1-4H3. InChi Key: BSNRAQZLNMHAOJ-UHFFFAOYSA-N.
