Methylene Blue Supplier in Malaysia
- Also known as
- Methylthioninium Chloride
- Basic Blue 9
- CI 52015
Methylene blue supplier enquiries in Malaysia cover industrial dye, laboratory reagent and microscopy staining requirements. Also known as methylthioninium chloride, Basic Blue 9 and CI 52015, the material is commonly supplied as a dark green to blue-green crystalline powder that produces a blue solution in water.
Buyers may request industrial dye grade for colouring or tracer work, laboratory reagent grade for analytical procedures, or microscopy staining grade in powder or prepared-solution form. Dye content, loss on drying, insoluble matter and solution clarity should be matched to the intended method rather than assumed from the product name.
Textile and paper users specify methylene blue for selected blue-colour applications. Laboratories use it as a biological stain and redox indicator, while manufacturers may use it as a visible marker or process tracer. It is not Brilliant Blue FCF, and the two dyes have different identities and uses.
Send the required grade, powder or solution form, specification, application, quantity and delivery location with your enquiry. Availability, packing, documentation and delivery timing are confirmed with the quotation.

Methylene Blue grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Industrial methylene blue dye | dark green to blue-green crystalline powder | — | Colouring, tracer and process-indicator duties where Basic Blue 9 is named in an industrial formulation or operating procedure. | Confirm the required pack format with the quotation. |
| Laboratory reagent grade methylene blue | crystalline powder or buyer-specified reagent solution | — | Redox indication, analytical work and general laboratory methods that specify methylene blue at a defined reagent quality. | Confirm powder or solution requirements with the quotation. |
| Microscopy staining grade methylene blue | staining powder or prepared solution | — | Biological and microscopy staining methods that name methylene blue and define the required dye content or solution preparation. | Confirm the required form and pack format with the quotation. |

Safety and handling
Store sealed, dry and protected from strong light and incompatible materials. Control dust during powder handling and follow the safety information for the quoted grade.
Common questions about methylene blue
Is methylene blue the same as Brilliant Blue FCF?
No. Methylene blue is Basic Blue 9, also called methylthioninium chloride. Brilliant Blue FCF is a different food colour identified as E133 and CI 42090. They are separate dyes and should not be substituted by name alone.
Which methylene blue grade should I request?
Industrial dye grade suits colour, tracer and process-indicator uses. Laboratory reagent or microscopy staining grades are selected when a test method defines dye quality, solution behaviour or purity. Send the method or current specification with the enquiry.
Can methylene blue be supplied as powder or prepared solution?
Both are genuine market forms. State whether the process needs crystalline powder or a prepared solution, together with the required concentration and grade. Available forms and packing are confirmed with the quotation.
What specification details matter for methylene blue?
Buyers commonly identify the Colour Index identity, dye content, loss on drying, insoluble matter and solution clarity. Include the limits used by your formulation or analytical method so the quoted grade can be assessed.
What information is needed for a methylene blue quotation?
Provide the grade, form, application, target specification, quantity and delivery location. List any required product documents at the same time so they can be checked for the offered material.
