Description
Selecting a chitosan material for laboratory research requires clear information about molecular weight, degree of deacetylation, source, and physical form. Without these parameters, researchers may be unable to determine whether a chitosan powder matches the requirements of their planned study.
CB0660 Chitosan is an Analysis Grade, crab shell-derived chitosan supplied as an off-white powder. It has a specified molecular weight range of 10–20 kDa and a degree of deacetylation of ≥90%, identifying it as a low-molecular-weight chitosan for laboratory research.
Also known as deacetylated chitin and Poly(D-glucosamine), this product has defined specifications for mesh size, pH, ash, moisture, insolubles, heavy metals, and microbial limits. It is supplied for laboratory research or industrial use only and is not intended for human or animal drug, diagnostic, or therapeutic use.

Applications
CB0660 is intended for researchers who require an Analysis Grade, low-molecular-weight chitosan with a defined source and degree of deacetylation. Its documented specifications allow users to evaluate the material against the requirements of a planned laboratory protocol.
- Low-molecular-weight chitosan research: Laboratory studies requiring a specified molecular weight range of 10–20 kDa.
- Deacetylated chitin studies: Research requiring chitosan with a degree of deacetylation of at least 90%.
- Crab shell-derived material research: Studies in which the biological source of the chitosan must be identified.
- Laboratory material evaluation: Comparison or qualification of chitosan powders based on molecular weight, deacetylation, mesh size, pH, and compositional specifications.
- Research formulation assessment: Evaluation as a research material where protocol-specific suitability is independently established by the user.
Application note: The available product documents do not provide viscosity or solubility specifications. Suitability for a particular solvent system, formulation, biological model, or downstream process must be evaluated by the researcher.
Safety and Handling
Avoid dust formation and use appropriate laboratory gloves and eye protection when handling this chitosan powder. Keep the container tightly closed and store it in a dry, well-ventilated place at room temperature.
The SDS classifies the material as toxic to aquatic life (H401). Avoid release to the environment, do not allow the product to enter drains, and dispose of the contents and container through an approved waste-disposal route.
Review the complete Safety Data Sheet before handling. The product is listed as not dangerous goods under DOT, IMDG, and IATA transport information.

FAQ
What is the molecular weight of CB0660 Chitosan?
CB0660 has a specified molecular weight range of 10–20 kDa. This defined range identifies it as a low-molecular-weight chitosan rather than a high-molecular-weight chitosan.
What does “≥90% deacetylated” mean?
The product specification lists “Purity (deacetylated)” as ≥90%. On this page, the value is presented as the degree of deacetylation to distinguish it from a general chemical-purity or assay value.
What is the source of this low-molecular-weight chitosan?
CB0660 Chitosan is derived from crab shell. Researchers should consider this identified biological source when evaluating the material for their laboratory protocol.
What are the common names for Chitosan CAS 9012-76-4?
The product is also identified as deacetylated chitin and Poly(D-glucosamine). Its CAS number is 9012-76-4.
Is this chitosan soluble in water or dilute acid?
The available COA does not provide a solubility specification, and the SDS lists water-solubility data as unavailable. No specific dissolution claim or preparation protocol should therefore be assumed from these documents.
Is viscosity information available for CB0660 Chitosan?
No viscosity value or viscosity test condition is provided in the available COA or SDS. Users requiring a defined viscosity specification should request additional technical information before purchase.
How should CB0660 Chitosan be stored?
Store the product at room temperature in a tightly closed container. Keep it in a dry, well-ventilated place and protect the powder from unnecessary moisture exposure.
What handling precautions apply to this chitosan powder?
Avoid generating or inhaling dust and use appropriate laboratory gloves and eye protection. The SDS states that the material is toxic to aquatic life, so it should not be released into drains or the environment.
Is CB0660 intended for medical, diagnostic, or therapeutic use?
No. CB0660 is intended for laboratory research use only. It is not intended for human or animal drug, diagnostic, or therapeutic use.
Where can I find the Chitosan COA and SDS?
The available COA and Safety Data Sheet are linked in the Documents section. The supplied COA is a general document without a lot number or completed lot-specific results.
For laboratory research or industrial use only. Not for human or animal drug, diagnostic, or therapeutic use.
