What is Methylene blue powder ?
Methylene blue is easily soluble in water, easy to cross the cell membrane, and relatively non-toxic. Since it was introduced into biology in the 19th century, methylene blue has been widely used: methylene blue is used as a dye in neuroanatomy and bacteriology; In biochemical research, it acts as an indicator of redox. As an antidote, Methylene blue powder is used to treat methemoglobinemia caused by poisoning such as Nitrite. At the same time, it is also used for cyanide poisoning and ifosfamide-induced encephalopathy.

What is the main purpose of Methylene blue powder ?
1. Medical and diagnostic uses
As an antidote, it promotes the reduction of methemoglobin to hemoglobin and restores its oxygen carrying capacity.
In some areas, it is used in combination with fast-acting products for malaria treatment.
Detoxification application: used for the treatment of some cyanide, nitrate and ifosfamide-related encephalopathy.
Intraoperative staining and indication: used for diagnosis and treatment operations such as tissue staining and optical development.
Important note: 5‑HT syndrome can be induced when used together with serotonergic psychiatric products, which should be strictly avoided;
2. Laboratory and scientific research purposes
Biological staining: It is widely used for microscopic observation and identification of bacteria, cells and tissues (classic histological/microbiological staining).
Redox indicator: It is used as an electron acceptor/indicator in various chemical and biochemical analysis.
Analysis and detection: used to determine anionic surfactants.
Nucleic acid staining: It can be used as DNA/RNA stain in agarose gel electrophoresis.
Probe and material research: as redox medium for optical probe, nano-porous material intercalation agent, photoelectrochemical imaging and other research.
3. Industrial and daily related uses
Textile and papermaking dyes: good for bast fibers such as hemp, flax and hemp, and also used for paper and leather; It can dye silk and wool, but it has poor light resistance.
Ink and coating: it is used to prepare ink, pigment/lake color and various coatings.
Aquaculture: It is used as a bactericidal/antifungal agent for disease prevention and control in fish tank/aquatic scene.
Environmental monitoring and treatment: Because it is a typical cationic dye, it is often used in wastewater treatment research.

FAQ:
Q1:What are the grades of methylene blue powder? What is the difference in use?
A1:Industrial grade (purity ≥98%): suitable for dyes, water treatment, textile printing and dyeing, etc., with economical price. Reagent grade (AR): For laboratory testing and biochemical analysis, COA and MSDS are required. Pharmaceutical grade (in line with USP/EP standard): used for pharmaceutical raw materials.
Q2: What are the storage conditions of Methylene blue powder ?
A2:Methylene blue is sensitive to light, and long-term exposure to ultraviolet light or strong light will accelerate its decomposition. It is the basic storage requirement of methylene blue powder to avoid light, seal and store in a cool and dry place.
Q3: How to choose packaging specifications ?
A3: Sample: 10g/50g/100g aluminum foil bag vacuum packed, moisture-proof and light-proof. Batch: 1kg/ bag (lined with double PE bag), 25kg/ cardboard barrel (with waterproof film).
