Product Name:ethyl 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)picolinate
English Name:ethyl 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)picolinate
CAS No.:741709-57-9
Aliases:ethyl 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine-2-carboxylate, 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine-2-carboxylic acid ethyl ester, ethyl 5-(pinacolboronato)picolinate
Molecular Formula:C14H20BNO4
Physical Properties:White to off-white solid at ambient temperature (some batches may appear as a pale yellow viscous liquid). Density approx. 1.08 g/cm³ (predicted), boiling point approx. 380°C (predicted), flash point approx. 184°C (predicted). Soluble in dichloromethane, tetrahydrofuran, methanol and other organic solvents; insoluble in water. Moisture-sensitive; store sealed in a cool, dry place protected from light.
Uses:This product is an ethyl picolinate derivative bearing a pinacol boronate ester moiety and is mainly used as a synthetic intermediate. It is commonly employed as an aryl boron source in Suzuki cross-coupling reactions to construct carbon-carbon bonds between pyridyl and aryl/heteroaryl groups. It is widely applied in the synthesis of pharmaceutical intermediates, agrochemicals, and OLED functional materials, and can also be used for late-stage functionalization of bioactive molecules containing pyridine rings.
Technical Specifications:
Molecular formula: C14H20BNO4; molecular weight: 277.12
Appearance: white to off-white solid or pale yellow viscous liquid
Assay (HPLC): ≥97.0%
Solubility: soluble in dichloromethane, tetrahydrofuran, N,N-dimethylformamide and other organic solvents; insoluble in water
Storage conditions: keep sealed and protected from light at 2–8°C, away from fire sources, strong oxidizing agents and moisture
