DIAZO BLUE B SALT - Introduction
CI 37235(CI 37235) is an organic pigment, also known as Blue No. 22. Its chemical name is methylene blue and its chemical formula is C37H34N6Na2O9S3.
CI 37235 is a blue powder with some solubility in water. Its main characteristics are light resistance, weather resistance and alkali resistance, so it is widely used in the dye and pigment industry. CI 37235 has good coloring performance and stability, and can be used for coloring color paints, plastics, rubbers, fibers, inks and dye formulations.
there are two main methods for preparing CI 37235: one is through the reaction of benzophenone dimethylimine (precursor of methylene blue) and methyl sodium bromide under alkaline conditions; The other is prepared by the primary amine substitution reaction of benzophenone.
Regarding safety information, according to available data, CI 37235 has low toxicity to humans, but it is still recommended to pay attention to personal protective measures to avoid inhalation of dust, contact with skin and eyes. In the use, storage and handling process should follow the corresponding safety procedures.
