-Boiling point: 624.2 ± 55.0 ° C (predicted value).

-Density: 1.697 ± 0.06 g/cm ⊃3; (predicted value).

-Storage conditions: Sealed and stored at room temperature.

-Solubility: Dissolve in chloroform (slightly soluble, requiring ultrasonic treatment), DMSO (slightly soluble), methanol (slightly soluble, requiring ultrasonic treatment).

-Form: Solid.

-Acidity coefficient (pKa): 13.90 ± 0.10 (predicted value).

-Color: White to off white.

2. * * Preparation method * *:

-Tetrahydroxymethylurea is formed by etherification of excess methanol with tetrahydroxymethylurea under acidic conditions, and distilled at a pH range of 5-7 to separate volatile substances. It is further hydroxymethylated and etherified to obtain tetrahydroxymethylurea.

3. * * Purpose * *:

-Tetrahydroxymethylurea is mainly used as a water treatment agent.

-It is also an additive for powder coatings, water-based coatings, and an intermediate for the multifunctional material compound guar ring.

-Tetrahydroxymethylurea is widely used in the pharmaceutical and food industries, including as a component of injections and oral medications, with moisturizing, liver protecting, and eye pressure reducing effects. It can be used to treat ophthalmic diseases such as cataracts and glaucoma. In addition, it can also be used as an antipyretic and analgesic to alleviate symptoms such as fever, headache, joint pain, and muscle pain. In the food industry, tetrahydroxymethylurea is widely used as a sweetener, moisturizer, and preservative in candies, cookies, ice cream, canned foods, and more.

4. * * Security * *:

-Tetrahydroxymethylurea is flammable and irritating in solid form. Harmful products during combustion include carbon monoxide, carbon dioxide, etc. Irritating to the skin, eyes, and respiratory system. The interaction with strong oxidants may lead to combustion.

Tetrahydroxymethylurea has become an indispensable compound in the chemical industry due to its unique chemical properties and wide range of applications.
