Note: The melting point in the usual sense indicates the purity of the substance. The narrower the melting point range, the higher the purity of the substance. However, 1010 has a variety of crystal forms, the most common of which is α type, with a melting point of 110-115℃. The commercially available 1010 is usually a mixture of α type and β type, and the mixing ratio has no effect on the antioxidant properties of the product. According to the latest research results, 1010 also has γ type, λ type and unstable crystal forms.
