PIBX CAS 1380548-11-7

【Chemical Name】
PIBX (Pyridine–IBX Complex), 1:1 complex of 2-iodoxybenzoic acid and pyridine.

【CAS No.】
1380548-11-7

【Molecular Formula】
C₁₂H₁₀INO₄ (C₇H₅IO₄ · C₅H₅N)

【Molecular Weight】
359.12 g/mol

【Product properties】
White to off‑white crystalline powder. Remarkably enhanced solubility in common organic solvents (DMSO, DMF, acetonitrile, ethyl acetate, etc.) compared to uncomplexed IBX. Mild, selective oxidant with improved thermal and handling stability. Low hygroscopicity.

【Storage】
Store in a tightly closed container, protected from light and moisture. Recommended temperature: 2 – 8 °C (refrigerated). Avoid prolonged exposure to heat or open air.

【Packing】
Available in standard laboratory sizes (1 g, 5 g, 25 g, 100 g) and bulk custom packaging upon request.

【Application】
Efficient oxidation of primary and secondary alcohols to aldehydes and ketones. Serves as a direct replacement for IBX in most oxidative transformations, offering faster reaction kinetics, higher conversion, and significantly reduced oxidant consumption. Ideal for pharmaceutical intermediates, fine chemicals, and scale‑up processes where solubility and cost matter.

【Product Specification】

• Assay (HPLC): ≥ 98.0 %

• Loss on drying: ≤ 0.5 %

• Free pyridine content: within acceptable limits (typically ≤ 0.5 %)

• Appearance: white to off‑white powder, free of visible impurities
