Cat No:CHCH-0024
Chitin is a nitrogen containing polysaccharide that occurs widely in nature, mainly in the shell of shrimp, crab and insects, in the cartilage of molluscs and in fungal cell walls, and it is the second most abundant natural polymer after cellulose. This industrial grade is purified from shrimp and crab shell and serves as the base raw material for chitosan, glucosamine hydrochloride and glucosamine sulphate, as well as for food and chemical intermediates.
| Brand | Eata Marisource |
| Product Grade | Industrial Grade |
| Chemical Name | Chitin (poly-beta-(1,4)-2-acetamido-2-deoxy-D-glucose) |
| Molecular Formula | (C8H13NO5)n |
| Molecular Weight | Approx. 203 g/mol per repeat unit (polydisperse polymer) |
| Physical Form | Flake or powder |
| Appearance | Off-white flake or powder |
| Color | Off-white |
| Odor | Odorless or with a slight characteristic odor |
| Solubility | Soluble in strong inorganic acids with partial chain degradation |
| Water Solubility | Insoluble in water |
| Solubility in Organic Solvents | Insoluble in weak inorganic acids, alkali and common organic solvents |
| Moisture (Loss on Drying) | Below 10% |
| Ash Content | Below 3.0% |
| Assay / Purity | Above 80% |
| Particle Size | Flake or powder |
| Lead (Pb) | Below 2 ppm |
| Arsenic (As) | Below 1 ppm |
| Storage Temperature | Ambient, 15-25 °C |
| Storage Conditions | Store in a cool, dry and well-ventilated place; keep the container tightly closed and protect from moisture and direct sunlight |
| Allergen & Dietary Statement | Derived from crustacean shell (shrimp and crab); not suitable for shellfish-allergic consumers. Non-GMO, not irradiated |
| Intended Use | Raw material for further manufacturing |
| Target Industries | Chitosan production, glucosamine production, food and chemical intermediates |
| Recommended Applications | Base raw material for chitosan, glucosamine hydrochloride and glucosamine sulphate; intermediate for food and chemical industry use |
| Handling & Safety | Handle as a fine powdered material; avoid dust formation and wear gloves, mask and eye protection |
| Chemical Class | Naturally occurring structural polysaccharide consisting largely of poly-N-acetylglucosamine |
| Structural Unit | beta-(1,4)-linked N-acetyl-D-glucosamine repeating units arranged in crystalline microfibrils |
| Functional Groups | Acetamido groups at C-2 with hydroxyl groups at C-3 and C-6 dominating the surface chemistry |
| Ionic Character | Essentially neutral; unlike chitosan it carries almost no free charge in aqueous media |
| Key Features | Assay above 80 percent supplied as flake or powder for conversion rather than direct application |
| Functional Benefits | Serves as the single upstream raw material for chitosan, glucosamine and their many derivatives |
| Mechanism of Action | Alkaline deacetylation converts the acetamido group to a free amine and unlocks chitosan behaviour |
| Typical End Products | Chitosan production batches, glucosamine hydrochloride and sulphate, food and chemical intermediates |
| Formulation Compatibility | Insoluble in water and common solvents, so it is dispersed rather than dissolved in most processes |
| Preparation & Dissolution Guidance | Requires special solvent systems or chemical conversion and is not intended for direct water dissolution |
| Reactivity & Derivatization | Acid hydrolysis gives glucosamine while deacetylation opens the route to chitosan and its salts |
| Stability Notes | Very stable in dry storage thanks to high crystallinity and resistance to microbial attack |
| Usage Precautions | Specify assay and physical form together because both drive downstream conversion yields |
| Environmental Profile | Upcycled from crustacean shell waste and fully biodegradable in soil and marine conditions |
| Analytical Methods | Assay by hydrolysis and titration; nitrogen by Kjeldahl; ash by gravimetric ignition |
