 Products Description of Sodium Hydroxymethanesulphinate CAS#149-44-0Sodium bisulfite formaldehyde is translucent white orthorhombic crystals or small pieces. Apparent density 1.80～1.85g/cm3. Easily soluble in water, slightly soluble in alcohol. It has extremely strong reducing properties under high temperature and can make the dyed color disappear, so it is known as the chemical book of hanging white blocks. It decomposes when exposed to acid, and decomposes at 120°C to produce toxic gases such as formaldehyde and hydrogen sulfide.

Products Description of 2-Mercaptobenzothiazole CAS#149-30-4Pale yellow monoclinic needles or flaky crystals with an unpleasant odor.

Urea CAS#57-13-6The urea molecule is planar in the crystal structure, but the geometry around the nitrogens is pyramidal in the gas-phase minimum-energy structure. In solid urea, the oxygen center is engaged in two N-H-O hydrogen bonds. The resulting dense and energetically favourable hydrogen-bond network is probably established at the cost of efficient molecular packing: The structure is quite open, the ribbons forming tunnels with square cross-section.

Products Description of Poly(methylhydrosiloxane) CAS#63148-57-2Polymethylhydrogensiloxane is a silicone oil used in biology and chemistry. Under the action of metal salt catalysts, it can cross-link into a film at low temperature, forming a waterproof film on the surface of various materials.

Products Description of Urea CAS#57-13-6When the temperature is below 20℃ and the relative humidity is below 70%, urea not only does not absorb moisture, but also evaporates water to reduce its water content; when the temperature exceeds 20℃ and the relative humidity is higher than 80%, it begins to absorb moisture, and in severe cases, it becomes a paste. When the air turns dry again, it will re-agglomerate, and its degree is second only to ammonium nitrate.

Products Description of Chlorobutanol CAS#57-15-8Colorless crystals. There are two types of crystals: containing half molecular crystal water and anhydrous. The melting point of the containing half molecular crystal water type is 78℃, slightly soluble in water (1:250), easily soluble in ethanol (1:1), glycerol (1:10), ether, chloroform and volatile oil. The melting point of the anhydrous type is 97℃, the boiling point is 167℃, and the 135℃ (32.7kPa).
