Measured values for Dichloromethane, and where each one comes from
31 measured values for 11 properties, read from 4 public databases. On 4 properties the records differ. Each reading is shown with its own record. Follow any record to read the value at its source.
Boiling point

- Hazardous Substances Data Bank (HSDB)
- In water, 13,000 mg/L at 25 °C

Partition coefficient (log Kow)
1 record
Indicates whether the substance accumulates in fat or in water, which drives the environmental sections.
- log Kow = 1.25
- Hazardous Substances Data Bank (HSDB)
Viscosity
1 record
Governs how far a spill spreads and how fast it soaks into a surface or a sorbent.
- 0.437 mPa.s at 20 °C
- Hazardous Substances Data Bank (HSDB)
Odour
4 records, each a different case
Odour is a warning property only. Many substances are hazardous well below the concentration you can smell.
- Sweet, pleasant odor, like chloroform
- Hazardous Substances Data Bank (HSDB)
- Chloroform like odor
- Hazardous Substances Data Bank (HSDB)
- Penetrating ether-like odor
- Hazardous Substances Data Bank (HSDB)
- Slightly sweet smell, similar to that of trichloromethane
- Hazardous Substances Data Bank (HSDB)
These are the public records read for Dichloromethane, published here unchanged. Where two records disagree, the draft you buy states the value and names the record behind it, so a reviewer can see what was chosen. Every draft needs review by a competent person before it is issued.
