XLogP3:-0.16
Appearance:4-thiapentanal appears as a colorless to amber liquid with an extremely foul and persistent odor. Slightly soluble in water and denser than water. Contact may slightly irritate skin, eyes and mucous membranes. Moderately toxic. Used as a food additive.
Density:1.03 g/cm3
Melting Point:-75 °C
Boiling Point:165 °C
Flash Point:142 °F
Refractive Index:1.456
Water Solubility:It is readily soluble in alcohol solvents such as ethanol, propylene and glycol oil.It is insoluble in water.
Storage Conditions:2-8°C
Vapor Pressure:760 mm Hg ( 165 °C)
Vapor Density:>1 (vs air)
Toxicity:Oral-rat LD50: 4400 mg/kg; Oral-Mouse LD50: 1620 mg/kg
Flammability characteristics:Open flame flammable; decomposes toxic sulfide gas in case of heat
Explosive limit:1.3-26.1%(V)
Odor:Powerful, onion, meat-like odor
Taste:Pleasant, warm, meat and soup-like flavor at low levels
Henrys Law Constant:Henry's Law constant = 3.92X10-7 atm-cu m/mol at 25 °C (est)
Experimental Properties:log Kow 0.34 at 20 °C, pH 7.4-7.8; VP: 53-100 Pa at 20 -27 °C; BP: 170.3 °C at 101.3 kPa; MP: -75 °C at 101.3 kPa; Relative density: 1.04 at 20 °C|When heated to decomposition, it emits toxic vapors of SOx|Hydroxy radical reaction rate constant = 5.28X10-11 cu cm/molec-sec at 25 °C (est)
Air and Water Reactions:Slightly soluble in water.
Reactive Group:Aldehydes
Reactivity Profile:Organosulfides, such as 4-THIAPENTANAL, are incompatible with acids, diazo and azo compounds, halocarbons, isocyanates, aldehydes, alkali metals, nitrides, hydrides, and other strong reducing agents. Reactions with these materials generate heat and in many cases hydrogen gas. Many of these compounds may liberate hydrogen sulfide upon decomposition or reaction with an acid.
Autoignition Temperature:491 °F (255 °C)|255 °C
Physical Dangers:The vapour is heavier than air and may travel along the ground; distant ignition possible.
