Product: Demecolcine Solution
Common Names: Colcemid, N-deacetyl-N-methylcolchicine
Common Use: Laboratory applications, research in cell division
Appearance: Usually a clear, colorless to pale yellow liquid
Relevant Users: Researchers, lab technicians, medical professionals handling cytogenetics
Typical Sectors: Academic labs, biotech research centers, cytogenetic clinics
Hazard Class: Acute toxicity — can be harmful if swallowed, inhaled, or absorbed through skin
Main Risks: Serious eye irritation, skin sensitation, carcinogenic potential
Notable Symptoms: Nausea, headache, respiratory irritation, convulsions in severe exposure
Routes of Exposure: Inhalation, skin contact, ingestion
Chronic Exposure: Potential to cause genetic defects, harmful to fertility
GHS Symbols: Skull and crossbones, health hazard pictogram
Main Ingredient: Demecolcine (Colcemid)
Chemical Formula: C22H25NO6
Concentration: Varies; often in the range of micrograms to milligrams per milliliter in aqueous buffer
Additional Components: Sterile water, possible buffer salts such as phosphate-buffered saline
Impurities: Minimal, based on research-grade requirements; usually not specified in standard preparations
Eye Contact: Rinse thoroughly with water, keep eyelids open, seek immediate medical attention
Skin Contact: Remove contaminated clothing, wash skin gently with soap and water
Inhalation: Move the individual to fresh air, support breathing as needed, seek emergency help if symptoms appear
Ingestion: Rinse mouth, avoid inducing vomiting unless directed by a medical professional, seek prompt medical care
Immediate Symptoms: Irritation, redness, difficulty breathing, nausea; address these without delay for any suspected exposure
Medical Support: Supportive care, symptomatic management; no specific antidote documented for demecolcine toxicity
Suitable Extinguishers: CO2, dry chemical powder, water mist, foam
Combustion Hazards: May produce toxic fumes of nitrogen oxides, carbon monoxide, carbon dioxide
Protective Gear for Firefighters: Self-contained breathing apparatus, full protective gear for skin and eyes
Firefighting Considerations: Cool exposed containers with water spray to prevent rupture, minimize direct contact with runoff
Explosion Risk: Not reported under normal lab use; high temperatures could cause pressurization of sealed containers
Personal Precautions: Wear gloves, laboratory coat, safety goggles, suitable mask if ventilation is insufficient
Environmental Precautions: Prevent discharge into drains, soil, or waterways
Containment: Absorb small spills with inert material (vermiculite or sand), collect for proper disposal
Cleaning Method: Use damp disposable towels, avoid raising dust or aerosol, ventilate area
Waste Handling: Place in clearly labeled hazardous waste containers, follow institutional hazardous waste protocols
Safe Handling: Handle inside chemical fume hood or biosafety cabinet, avoid inhalation and contact with skin or eyes, never pipette by mouth
Storage: Store in tightly closed container, ideally refrigeration as recommended by supplier; away from heat, light, incompatible substances such as strong oxidizers
Labeling: Mark with clear hazard signage, restrict storage access to trained staff
Incompatibilities: Acidic, alkaline, or oxidizing materials
Transport Within Facility: Use sealed secondary containers, minimize potential for breakage or spillage
Engineering Controls: Work with local exhaust ventilation, make use of fume hoods where possible
Personal Protection: Nitrile, latex, or equivalent chemical-resistant gloves; laboratory coat or gown; safety goggles or face shield
Respiratory Protection: Use NIOSH-approved mask or respirator if aerosolization is possible
Hygiene Measures: Wash hands thoroughly after use, prohibit eating, drinking, or smoking in work area
Exposure Limits: No established OSHA or ACGIH limits, treat as high toxicity compound by minimizing exposure as much as possible
Physical State: Typically liquid in diluted commercial form
Color: Clear to pale yellow
Odor: Almost odorless
Solubility: Readily soluble in water
Boiling Point: Not typically specified for solutions; demecolcine solid decomposes before boiling
Melting Point: Not typically relevant for sold solutions
pH (for solution): Slightly acidic to neutral depending on buffer
Vapor Pressure: Not significant at room temperature for dilute solutions
Chemical Stability: Stable under normal laboratory conditions, especially with refrigeration and away from light
Decomposition Products: Nitrogen oxides, carbon monoxide, carbon dioxide if heated to decomposition
Incompatible Materials: Strong acids, bases, oxidizers — rapid breakdown or hazardous byproducts may result
Conditions to Avoid: Prolonged exposure to heat, light, strong oxidizing environments
Polymerization: Not reported to occur under standard handling
Routes of Exposure: Inhalation, ingestion, skin absorption
Acute Effects: Vomiting, abdominal pain, respiratory distress, neurological symptoms in serious cases
Chronic Effects: Risks for mutagenicity, potential carcinogenic properties from long-term lab animal studies
Target Organs: Liver, kidneys, bone marrow, reproductive organs, nervous system
Lab Animal Data: Demonstrates cytotoxicity related to cell division interference
Human Data: Avoided unless absolutely necessary for specific medical procedures or research
Persistence: Likely to persist in the environment, as cytotoxic compounds do not easily degrade
Bioaccumulation: Not enough human field data, but toxicity to aquatic organisms is a concern
Water Hazard: Significant; must not reach surface water or soil
Mobility in Soil: Limited information, but concern remains over groundwater contamination
Disposal Needs: Thorough deactivation or incineration; never flush to drain
Disposal Method: Collect waste in clearly marked, leak-proof hazardous waste containers
Incineration: Recommended at a licensed chemical disposal facility
Non-Incineration Disposal: Chemical deactivation if approved by environmental health and safety guidelines
Legislation: Comply with national, local, and institutional hazardous waste management rules
Lab Practices: Minimize waste, segregate sharps, contaminated tools, and PPE separately
Regulation Status: Classified as a hazardous material for shipping
Packing: Secondary leak-proof containers inside rigid outer packaging
Transportation Restrictions: Comply with relevant land, air, and sea transport rules
Spill Contingency: Carry spill kits and hazard labels during all stages of transit
Compatibility: Avoid packing with strong acids, bases, or oxidizers to prevent inadvertent reactions
Global Status: Subject to regulations for toxic laboratory reagents under GHS, OSHA Hazard Communication Standard where applicable
Restricted Activities: Usage limited to licensed labs, trained personnel
Labeling: Safety symbols and explicit hazard wording are required on all primary and secondary containers
Oversight: Institutional review, regular compliance audits, strict documentation for usage and disposal
Worker Safety: Mandated annual safety training and exposure monitoring for staff with hands-on access
