Chemical Name: Isobutyramide stands out as a chemical compound often seen in laboratories and small-scale syntheses.
Common Synonyms: 2-Methylpropanamide is another name you might notice on bottles and paperwork.
Chemical Formula: C4H9NO sets out the atomic makeup.
CAS Number: 563-83-9 points to a clear identifier in chemical registries.
Appearance: Often shows up as a white powder or crystalline solid.
Odor: Slight earthy or amide-type smell that’s not sharp or overpowering.
GHS Classification: Causes mild skin and eye irritation but rarely more severe outcomes.
Hazard Statements: Exposure carries low acute toxicity, but prolonged contact may dry skin or cause discomfort.
Pictogram: Standard exclamation mark for irritants.
Precautionary Guidance: Use in a well-ventilated space, don gloves and goggles, and avoid creating dust clouds. Inhalation should be minimized.
Main Ingredient: Isobutyramide comprises nearly the entirety of preparations, frequently listed at more than 98% purity in chemical supply.
Impurities: Most batches contain trace amounts of related amides or by-products from synthesis, which do not typically pose additional health concerns at these levels.
Physical Form: Powder or small crystals tend to characterize most shipments.
Inhalation: Remove the person to fresh air; if symptoms persist, medical attention may become necessary for ongoing irritation or respiratory discomfort.
Skin Contact: Wash with soap and water thoroughly; irritation should subside, but broken skin may need further observation.
Eye Contact: Rinse under running water for several minutes, keeping eyelids open and avoid rubbing.
Ingestion: Rinse mouth and drink water. Monitor for symptoms like nausea; severe effects remain rare. Medical evaluation for accidental large intakes is advised.
Suitable Extinguishing Media: Water spray, foam, dry chemical, or carbon dioxide effectively tackle small fires around dry Isobutyramide.
Specific Hazards: Combustion emits carbon monoxide, nitrogen oxides, and sometimes irritating amide fumes.
Firefighting Advice: Warehouse fires call for self-contained breathing apparatus and full protective gear. A fire near this chemical often needs efficient ventilation.
Precautions: Remove unaffected containers from fire area if safe to do so.
Personal Protective Gear: Wear gloves, goggles, and an appropriate dust mask before touching powder or crystals.
Clean-Up Approach: Scoop spills into an appropriate container with non-sparking tools. Avoid sweeping, which will raise dust.
Environmental Response: Do not allow large quantities of powder to enter drains, soil, or watercourses.
Ventilation: Air out the area well, especially if a cloud has formed from an accidental knock-over.
Handling Practices: Feedstock should only be handled with gloves and eye protection in rooms with decent airflow.
Storage Locations: Store in a tightly sealed, labeled container away from sunlight, heat, and sources of ignition.
Incompatible Materials: Contact with strong acids, bases, or oxidizers can lead to unwanted reactions. A typical chemical shelf in a cool, dry lab works best.
General Principles: Maintain order—segregate from active acids, peroxides, or hypochlorites.
Exposure Limits: No established regulatory exposure limits exist in many jurisdictions, but minimizing inhalation and direct skin absorption still makes sense.
Engineering Controls: A chemical fume hood allows for safe handling, especially in larger or repeated quantities.
Personal Protective Gear: Gloves (nitrile or similar), snug goggles, and a dust mask or respirator for weighing and mixing. Lab coats keep powder off clothing.
Hygiene Tips: Wash hands after handling, and avoid eating or drinking near workstations.
Appearance: White to off-white powder, usually odorless or faintly amine-like.
Melting Point: Frequently reported around 110-115°C.
Solubility: Dissolves modestly in water, more readily in organic solvents like ethanol and acetone.
Relative Density: Sits close to 1.0 g/cm3, making it neither especially heavy nor light for a solid.
Vapor Pressure: Low under ambient temperatures, so vapor hazards remain minimal.
Chemical Stability: Stable under most storage and handling conditions, provided moisture and high heat stay away.
Reactive Conditions: Avoid strong acids, bases, oxidizing agents; violent or rapid reactions might occur if a spill contacts these.
Thermal Decomposition: Yields irritant and toxic vapors, so burning or heating beyond recommended limits presents notable risk.
Routes of Exposure: Includes inhalation, skin and eye contact, accidental ingestion.
Acute Effects: Skin and eye contact may lead to redness or discomfort, but symptoms usually resolve on their own.
Repeated Exposure: Limited long-term data, though extended or high-frequency contact is best avoided on the chance of cumulative skin dryness or minor respiratory effects.
Carcinogenicity and Mutagenicity: No major agencies list isobutyramide as a probable or suspected carcinogen.
Environmental Fate: Likely degrades slowly in the environment, though direct evidence remains sparse.
Ecotoxicity: Low expected toxicity to aquatic organisms at small concentrations, but larger spills into streams or soil could disrupt local biological routines.
Persistence and Bioaccumulation: Bioaccumulation does not pose a significant risk based on available studies.
Waste Treatment: Collect spills and residues in sealed containers for disposal at a licensed chemical facility.
Guidance: Do not discharge into sewers or environment. Disposal by incineration often meets local regulations and offers a controlled method.
Recycling or Reuse: Unused compound in uncontaminated form may be eligible for reuse within the facility if purity meets specification and risk remains manageable.
Hazard Class: Not regulated as a dangerous good by the majority of transport agencies for small quantities.
Shipping Instructions: Ship in a tightly sealed, labeled container, often within secondary containment that can withstand breakage or leaks.
Environmental Precautions: Spills in transit should be contained and cleaned up according to local guidance for chemical spills.
Labeling: Labels often provide hazard pictograms for irritants and cautionary advice in accordance with GHS or similar regional standards.
Inventory Listings: Commonly listed on country-level chemical inventories such as TSCA in the US or EINECS in Europe.
Worker Protection: Most jurisdictions require worker training and laboratory hazard communication as part of sound chemical management practices.
Additional Requirements: Waste disposal and transport follow standard procedures for laboratory chemicals; no significant additional regulatory hurdles appear for most research-level uses.
