The Paraformaldehyde, with the cas register number 30525-89-4, has its IUPAC name of formaldehyde. This is White solid, with the similar smell with formaldehyde. And it is insoluble in ethanol and ethyl ether while soluble in caustic soda. This chemical is stable while incompatible with strong acids, organic acids, strong oxidizing agents, oxides, alkalies, strong bases, amines. Besides, its product categories are including Polymers.
The characteristics of this chemical are as below: (1)XLogP3-AA: 1.2; (2)H-Bond Donor: 0; (3)H-Bond Acceptor: 1; (4)Rotatable Bond Count: 0; (5)Exact Mass: 30.010565; (6)MonoIsotopic Mass: 30.010565; (7)Topological Polar Surface Area: 17.1; (8)Heavy Atom Count: 2; (9)Formal Charge: 0; (10)Complexity: 2; (11)Covalently-Bonded Unit Count: 1.
As to its usage, it is widely applied in many ways. It could be used in pestide, such as in synthesis of acetochlor, butachlor and glyphosate; It could be used in painting, such as in synthesis for top-grade car; It could be used in composing urea resin, phenolic resin, Polyacetal Resin, ion exchange resin and other kinds of adhesive; It could also be used in papermaking, foundry, fishi breeding and poultry raising, organic material, adn others like pharmaceutic and disinfection.
You should be cautious while dealing with this chemical: For being a kind of harmful chemical, it may cause damage to health, and may cause sensitisation by skin contact. Then it is irritating to eyes, respiratory system and skin, and if by inhalation, in contact with skin or if swallowed, it will be very dangerous. Besides, contacting with acids liberates toxic gas and it could even have limited evidence of a carcinogenic effect. So you should take the following instructions while using. Wear suitable protective clothing, gloves and eye/face protection. And if in case of accident or if you feel unwell seek medical advice immediately (show the label where possible), and if in case of contacting with eyes, rinse immediately with plenty of water and seek medical advice. And lastly, do not breathe dust.
The following datas could be converted into the molecular structure:
