Alloimperatorin 98% Purity Furocoumarin Standard CAS 642-05-7 Research Grade Reference Standard

• • • • • • Product Overview

            Alloimperatorin is a naturally occurring furocoumarin found in the roots of Angelica dahurica (Bai Zhi) and other plants. It is a positional isomer of imperatorin and serves as an important reference standard for the quality control of Bai Zhi products.

            With the molecular formula C₁₆H₁₄O₄ and a molecular weight of 270.28 g/mol, this compound appears as a white to off-white crystalline powder. It is soluble in methanol, ethanol, and DMSO. The product is supplied at ≥98% purity as determined by HPLC analysis.

            Synthetic Process

            Alloimperatorin is obtained through isolation from plant sources:

            1. Extraction: Angelica dahurica roots are extracted with organic solvents.

            2. Chromatographic Separation: The extract is fractionated using silica gel column chromatography.

            3. Purification: Preparative HPLC or recrystallization yields the pure compound.

            4. Identity Confirmation: Structure is confirmed by NMR and mass spectrometry.
