69804-48-4 Usage
Uses
Used in Sunscreen Products:
4,4'-bis[(2-hydroxyethyl)methylamino]benzophenone is used as a UV filter in sunscreen products for its ability to absorb and dissipate UV radiation, providing protection against the harmful effects of the sun.
Used in Personal Care Products:
In addition to sunscreens, Benzophenone-5 is also used in other personal care products, such as lotions, creams, and makeup, to offer UV protection and prevent skin damage caused by sun exposure.
Used in Regulatory Compliance:
Due to concerns about Benzophenone-5's potential to cause skin sensitization and its impact on aquatic environments, some countries have restricted its use in certain products. Manufacturers must adhere to these regulations to ensure the safety and environmental friendliness of their products.
Check Digit Verification of cas no
The CAS Registry Mumber 69804-48-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,8,0 and 4 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 69804-48:
(7*6)+(6*9)+(5*8)+(4*0)+(3*4)+(2*4)+(1*8)=164
164 % 10 = 4
So 69804-48-4 is a valid CAS Registry Number.

Method for preparing 4,4'-di[(2-hydroxyethyl)methylamino]benzophenone
-
Paragraph 0021-0033, (2019/02/04)
The invention relates to the field of organic synthesis, and discloses a method for preparing 4,4'-di[(2-hydroxyethyl)methylamino]benzophenone. The method comprises the following steps: dissolving rawmaterials including at least one of 4,4'-dichlorobenzophenone and 4,4'-difluorobenzophenone, as well as N-methyl-2-hydroxyethylamine in a reaction solvent, and adding an acid catalyst; heating and refluxing to react, insulating to react, adding a solvent, cooling to 0-5 DEG C, insulating to separate crystals, washing and drying to obtain the product. The method adopting industrial conventional raw materials has mild reacting conditions, simple reacting process, simple post-treatment, less 'three wastes' and high yield and can meet the environment-friendly chemical requirement.
