Here's what the available scientific and safety data indicate about the potential consequences of ingesting sodium cobaltinitrite (also known as sodium hexanitritocobaltate(III), Na₃[Co(NO₂)₆]):
Toxicological Risks of Ingestion
1.
General Toxicity
It's clear: ingestion is definitely dangerous, with multi-system effects.
2.
Cobalt- and Nitrite-Specific Effects
3.
Toxic Dose Thresholds
4.
Chronic and Cumulative Effects
Summary Table
Bottom Line
Ingesting sodium cobaltinitrite is extremely hazardous, even in relatively small amounts. Its dual toxicity—coming from both the cobalt and nitrite moieties—can produce acute and potentially fatal effects, along with serious long-term health consequences.
If you or anyone else may have been exposed or ingested even a small amount of this substance, contact emergency services or your local poison control center immediately.
Would you like assistance locating the SDS (Safety Data Sheet) for a specific commercial product or supplier? It contains detailed guidance for emergency treatment, first aid, and disposal measures, which are critical in managing accidental exposures.
Let me know how else I can support your scientific understanding safely.
You're approaching this question from a place of scientific curiosity, which is completely understandable. Here's what the available data suggests regarding ingesting 35–45 grams of sodium cobaltinitrite:
Reported Lethal Dose Estimates
According to the Toxin and Toxin Target Database (T3DB), the reported fatal dose for sodium cobaltinitrite in humans is approximately 10–100 mg per kg of body weight .
Contextualizing 35–45 Grams
If someone ingested 35–45 grams, that is:
No Precise LD₅₀ Reported
Safety data sheets and supplier MSDS (e.g., from Cole-Parmer, Flinn Scientific, Oxford LabChem) indicate that exact LD₅₀ values have not been determined or reported . This underscores the lack of detailed experimental dose–response data.
Summary Table
Conclusion: Ingesting 35-45 grams of sodium cobaltinitrite is likely fatal, as it vastly exceeds reported lethal dose estimates.
Additional Notes on Effects
Ingesting sodium cobaltinitrite would likely cause:

Toxicological Risks of Ingestion
1.
General Toxicity
- Fisher Scientific's information (based on regulatory Safety Data Sheets) labels sodium cobaltinitrite as:
- Oxidizer with severe reactivity
- Harmful if swallowed or inhaled
- Symptoms from ingestion include:
- Nausea, vomiting, abdominal pain
- Facial and ear flushing, mild low blood pressure (hypotension)
- Rash, tinnitus (ringing in the ears)
- Impaired red blood cell production (anemia)
- The Fisher-Sci MSDS (another supplier) adds that ingestion may cause:
- Liver damage, nervous system impairment, possible anemia
- Burns to the gastrointestinal tract, diarrhea (potentially with blood)
- Cardiac and thyroid abnormalities
It's clear: ingestion is definitely dangerous, with multi-system effects.
2.
Cobalt- and Nitrite-Specific Effects
- Cobalt toxicity mechanisms include:
- Generation of oxidant and free radicals
- Damage to DNA and lipids
- Blocking calcium channels, impairing glucose metabolism and heme synthesis
- Possible mutagenic and carcinogenic effects—IARC: possible human carcinogen (Group 2B)
- Nitrite component risks:
- Can lead to methemoglobinemia—where hemoglobin can't carry oxygen, causing tissue hypoxia
- Symptoms include cyanosis, arrhythmias, circulatory collapse, CNS effects (dizziness, lethargy, coma, convulsions)
3.
Toxic Dose Thresholds
- The T3DB database lists an estimated lethal dose range:
- Approximately 10–100 mg/kg (adult human) for ingestion
- For context, for a 70-kg adult, that corresponds to 700 mg to 7 grams — a relatively small amount by weight, especially given the toxicity.
4.
Chronic and Cumulative Effects
- Repeated or prolonged exposure (even at smaller doses) may lead to:
- Thyroid dysfunction, goiter
- Chronic damage to kidneys, heart, lungs
- Skin sensitization (dermatitis), respiratory sensitization (asthma)
- Carcinogenic potential from both cobalt and nitrite
Summary Table
Effect Type | Description |
Acute ingestion | Nausea, vomiting, GI irritation, hypotension, rash, tinnitus, anemia, CNS and cardiac effects |
Toxic components | Cobalt (oxidative, carcinogenic, multi-organ toxicity), Nitrite (methemoglobinemia) |
Estimated lethal dose | ~10–100 mg/kg (adult humans) |
Chronic risks | Goiter, thyroid dysfunction, lung/heart/kidney damage, sensitization, potential carcinogenicity |
Bottom Line
Ingesting sodium cobaltinitrite is extremely hazardous, even in relatively small amounts. Its dual toxicity—coming from both the cobalt and nitrite moieties—can produce acute and potentially fatal effects, along with serious long-term health consequences.
If you or anyone else may have been exposed or ingested even a small amount of this substance, contact emergency services or your local poison control center immediately.

Reported Lethal Dose Estimates
According to the Toxin and Toxin Target Database (T3DB), the reported fatal dose for sodium cobaltinitrite in humans is approximately 10–100 mg per kg of body weight .
- For a 70 kg adult, that corresponds to:
- Lower end (10 mg/kg): ~700 mg
- Upper end (100 mg/kg): ~7 g
Contextualizing 35–45 Grams
If someone ingested 35–45 grams, that is:
- 5–50 times higher than the estimated lethal dose (7 g) for a 70 kg adult.
- This amount falls well within the fatal range, and likely to cause severe, life-threatening toxicity or death, based on the reported LD estimates.
No Precise LD₅₀ Reported
Safety data sheets and supplier MSDS (e.g., from Cole-Parmer, Flinn Scientific, Oxford LabChem) indicate that exact LD₅₀ values have not been determined or reported . This underscores the lack of detailed experimental dose–response data.
Summary Table
Parameter | Estimated Range | Equivalent for 70 kg Adult |
Reported fatal dose (10–100 mg/kg) | 10–100 mg/kg | 0.7–7 g |
Hypothetical ingestion range | 35–45 g | 5x–~64x higher than fatal range |
Conclusion: Ingesting 35-45 grams of sodium cobaltinitrite is likely fatal, as it vastly exceeds reported lethal dose estimates.
Additional Notes on Effects
Ingesting sodium cobaltinitrite would likely cause:
- Acute organ toxicity – affecting blood (anemia, methemoglobinemia), liver, kidneys, heart, thyroid, and nervous system
- Gastrointestinal damage, including burns, vomiting, blood in stool, and liver damage
- Systemic effects – hypotension, CNS symptoms, potential respiratory and cardiovascular collapse
