Molecular formula can be customized according to user needs: C₁₇H₁₃NO₈S₂=423.42

A simple method to distinguish the authenticity and quality of methyl imine-H:

At first glance, the appearance: Imine-H is in powder form, and after synthesis, it is in a fine powder state without the need for grinding. Any product with lumps is considered to be of poor quality;

Second look at color: Imine-H is orange(Orange)Yellow to Orange(Orange)Red, the redder the color, the higher the purity. If the color is yellow, it is considered an unqualified product;

Three considerations for bulk density: Imine-H has a relatively light texture, and typically a 50mL bottle can hold up to 12-13 grams. Any 50mL bottle that contains 20g or more is considered defective;

Four looks at the packaging: Imine-H is used to measure boron, and glass contains boron, so Imine-HCannot be bottled in glass bottlesCan only be packaged in plastic bottles and sealed with aluminum foil bags.
