Chitosan History

It was in the 1980s when the reserch and applications in agriculture and horticulture is begin.

Chitosan Specification

The Chitosan, with the cas registry number 9012-76-4, is a kind of white colorless solid. This is stable but incompatible with strong oxidizing agents. And its product categories are including Miscellaneous Natural Products; Biochemistry; Polysaccharides; Sugars; Nutritional Supplements; Dextrins Sugar & Carbohydrates.

The physical properties of this chemical are as follows: (1)# of Rule of 5 Violations: 3; (2)ACD/BCF (pH 5.5): 1; (3)ACD/BCF (pH 7.4): 1; (4)ACD/KOC (pH 5.5): 1; (5)ACD/KOC (pH 7.4): 1; (6)#H bond acceptors: 48; (7)#H bond donors: 37; (8)#Freely Rotating Bonds: 55; (9)Polar Surface Area: 808; (10)Index of Refraction: 1.701; (11)Molar Refractivity: 336.803 cm3; (12)Molar Volume: 870.564 cm3; (13)Polarizability: 133.519 ×10-24 cm3; (14)Surface Tension: 122.211 dyne/cm; (15)Density: 1.753 g/cm3; (16)Exact Mass: 179.079373; (17)MonoIsotopic Mass: 179.079373; (18)Topological Polar Surface Area: 116; (19)Heavy Atom Count: 12; (20)Complexity: 155.

The production method of this chemical is below: Add 20g Chitosan into the 300mL 50% NaOH solvent and wait for its complete infiltration; Then heat to 95℃ for about 1.5 hours, filter out the alkali liquor and then wash to be neutral; Lastly cool and dry to have colorless transparent schistose products 15.6g.

As to its usage, it is widely applied in many ways. It could be used as antistaling agent which is usually used in food industry, and thickening agent, flocculating agent; It could also be used in pharmaceutic, agricultural seed, daily expenses, waste water treatment.

When you are dealing with this chemical, you should be very cautious. Being a kind of harmful chemicals, it may cause damage to health. If by inhalation, in contact with skin and if swallowed, it is dangerous. Then it is irritating to eyes, respiratory system and skin. Therefore, you shoud take the following instructions. Wear suitable protective clothing, and then avoid contacting with skin and eyes. If in case of contact with eyes, rinse immediately with plenty of water and seek medical advice.

In addition, you could convert the following datas into the molecular structure:
(1)Canonical SMILES: C(C1C(C(C(C(O1)O)N)O)O)O
(2)Isomeric SMILES: C([C@@H]1[C@H]([C@@H]([C@H]([C@@H](O1)O)N)O)O)O
(3)InChI: InChI=1S/C6H13NO5/c7-3-5(10)4(9)2(1-8)12-6(3)11/h2-6,8-11H,1,7H2/t2-,3-,4-,5-,-/m1/s1
