What is Methanol-¹³C (¹³CH₃OH)?

Methanol-¹³C (¹³CH₃OH) is a molecule of methanol in which the carbon atom is the carbon-13 isotope (¹³C) rather than the more common carbon-12 (¹²C). It is a clear, colorless, volatile liquid that is highly flammable and toxic. Its molecular weight is approximately 33.03 g/mol (ordinary ¹²CH₃OH: ~32.04 g/mol). This small mass difference, together with the NMR-active nature of the ¹³C nucleus (spin I = 1/2), makes ¹³CH₃OH an exceptionally powerful non-radioactive stable isotope tracer and a standard reference material for tracking carbon atoms through complex chemical and biological systems.

What are applications of Methanol-¹³C (¹³CH₃OH)?

Methanol-¹³C (¹³CH₃OH) is a highly versatile stable isotope tracer. Because the ¹³C isotope is non-radioactive and can be easily detected by advanced instruments, it serves as a critical building block across pharmaceutical, scientific, and analytical fields.

1. Pharmaceutical R&D

Core Starting Material: It is used as a primary starting material for the synthesis of ¹³C-labeled drugs.
Intermediates & Standards: It is essential for preparing various labeled pharmaceutical intermediates and drug metabolite standards.
Supporting Critical Studies: These labeled compounds support crucial research such as pharmacokinetics (PK) and bioequivalence (BE) studies. By using ¹³C-labeled methanol, researchers can accurately track how a drug is absorbed, distributed, metabolized, and excreted in the body.

2. Organic & Life Sciences Research

Fundamental Tracing Building Block: As a foundational isotopic tracing building block, it is widely applied in cutting-edge scientific experiments.
Reaction Mechanisms: Chemists use it to investigate organic reaction mechanisms, tracking exactly where a methyl group attaches during a chemical transformation.
Metabolic Pathway Tracing: In biological research, it is used to trace metabolic pathways and understand how carbon flows through complex living systems.

3. Analytical Testing & Quality Control

Internal Standards & Calibration: It is widely used to formulate isotope internal standard reagents and calibration standard solutions.
Precision Analysis: It is highly compatible with various precision analytical scenarios, such as Mass Spectrometry (MS) and Chromatography (GC/LC). Using ¹³CH₃OH as an internal standard helps eliminate matrix effects and instrument fluctuations, ensuring highly accurate and reliable quantitative results in fields like environmental monitoring, food safety, and clinical diagnostics.

Frequently Asked Questions (FAQs)

Q1. What is Methanol-¹³C (¹³CH₃OH) in simple terms?
A: It is a special type of alcohol liquid (methanol). The carbon inside it is a natural, slightly different kind of carbon (Carbon-13) that can be easily detected by special laboratory machines. This makes it very useful for tracking.

Q2. What is it mainly used for?
A: It is used in medical research, industrial testing, and general scientific studies. Researchers use it to track how carbon moves and changes in different processes.

Q3. Is it natural or radioactive?
A: It is completely natural and not radioactive at all. Carbon-13 is naturally found in all living things and everyday materials. We simply concentrate it to make this product.

Q4. How should it be stored?
A: It must be kept in a securely sealed glass bottle. You should store it in a cool, dry, and safe place, away from fire, heat, and sunlight.

Q5. Is it safe to handle?
A: No, it must be handled with great care. Just like regular methanol, it is highly toxic if swallowed or inhaled, and extremely flammable. It must only be used by trained professionals in well-ventilated areas (like a fume hood).

Q6. Is it bad for the environment?
A: It is not a fluorinated gas. However, it is a toxic chemical, so it should be handled carefully to avoid unnecessary spills. It must be disposed of according to local chemical waste regulations.

Q7. Are there special rules for shipping it?
A: Yes. Because it is a toxic and flammable liquid, it is classified as a hazardous material. It must be transported safely in approved containers by trained professionals.

Q8. How pure is this product?
A: Our product is highly pure. It is available in high concentrations, and we can provide custom purity levels if needed.

Q9. Why is it useful for research?
A: It acts like a tiny “tracking tag.” Because special machines can easily see it, scientists can follow exactly where the carbon goes during tests without disturbing the process.

Q10. Why choose this instead of regular methanol?
A: You only choose this if you need to track the carbon. It is not safer than regular methanol—it is just easier for machines to detect. If you don’t need to track it, regular methanol is enough.
