In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Use of chemicals for the preservation of polychromed wood, published in 1988-01-31, which mentions a compound: 4897-25-0, mainly applied to polychrome wood preservation chem, SDS of cas: 4897-25-0.
Polychromed wood was examined and pigments used were applied to Picea excelsa blocks on bases used for making original art objects. The samples were impregnated with Antox W (p-coumylophenol + methoxychlor), Xyligen Al (I), Vitavax, or PCMNI (II) and effects on dominant wavelength, colorimetric purity, and the degree of clarity were determined I caused the least darkening of the pigments.
The article 《Use of chemicals for the preservation of polychromed wood》 also mentions many details about this compound(4897-25-0)SDS of cas: 4897-25-0, you can pay attention to it, because details determine success or failure
