Cat No:CHCH-0094
A high-purity chitin refined to protein at or below 3.0% and ash at or below 2.0%, delivered as a slightly yellow flake or powder. The polymer stays insoluble in water and common solvents but dissolves in LiCl/DMAc and concentrated acids for downstream conversion.
| Brand | Eata Marisource |
| Product Grade | High Purity / Biomedical Feedstock |
| Chemical Name | Chitin (poly-N-acetylglucosamine) |
| Molecular Formula | (C8H13NO5)n |
| Molecular Weight | Grade-dependent |
| Raw Material Source | Crustacean shell |
| Physical Form | Flake or powder |
| Appearance | Slightly yellow |
| Odor | Odorless |
| Solubility | Soluble in 8% LiCl/DMAc and concentrated acids; insoluble in water, dilute acid, alkali, ethanol and common organics |
| Moisture (Loss on Drying) | ≤10.0% |
| Ash Content | ≤2.0% |
| Intended Use | Chitosan conversion feedstock, biomedical materials, industrial and agricultural applications |
| Target Industries | Biomedical, textiles, water treatment, agriculture, cosmetics |
| Recommended Applications | Precursor to fibers, films, sutures, dialysis membranes and vascular grafts; insecticide and antiviral agro bases; cosmetic moisturizer feedstock |
| Recommended Use Level | Feedstock dosing per conversion route |
| Appearance of Solution | Dissolve in LiCl/DMAc or concentrated acid media under controlled temperature |
| Handling & Safety | Keep dry; avoid strong oxidizers |
| Chemical Class | Acetylated aminopolysaccharide |
| Structural Unit | β-(1→4)-linked N-acetyl-D-glucosamine |
| Functional Groups | Acetamido and hydroxyl groups |
| Ionic Character | Neutral polymer |
| Key Features | Protein ≤3.0%; ash ≤2.0%; defined solvent routes for regeneration and spinning |
| Functional Benefits | Low residual protein supports biomedical conversion; the classic gateway polymer to chitosan and chitin nanomaterials |
| Mechanism of Action | Acetamido backbone provides structural rigidity; dissolution routes regenerate chitin into fibers, films and scaffolds |
| Typical End Products | Contact lenses, artificial skin, sutures, dialysis membranes, vascular grafts, specialty textiles |
| Formulation Compatibility | Processing via LiCl/DMAc, ionic liquids or acid media per downstream design |
| Preparation & Dissolution Guidance | Dry before dissolution; control acid exposure time to protect chain length |
| Reactivity & Derivatization | Acetamido groups hydrolyze toward chitosan; hydroxyls support esterification |
| Stability Notes | Very stable as dry flake; inert across wide pH in solid state |
| Usage Precautions | Solvent dissolution involves hazardous media: industrial controls required |
| Environmental Profile | Marine by-product valorization at industrial scale |
| Analytical Methods | Protein; ash; moisture; acetylation degree; solvent-solubility check |
