Description of key information

Appearance:

Based on available data from authoritative database,the chemical Methyl methanesulphonate was observed to be  is a colourless to yellowish organic liquid  in appearance having pungent odour.

Freezing point:

Based on available data from various reliable sources such as authoritative databases,review articles and handbook,the freezing point of chemical Methyl methanesulfonate was determined to be 20 degree C.

Boiling point:

Based on available data from various reliable sources such as authoritative database and  handbook, the boiling point of  chemical Methyl methanesulfonate was determined to be 203 degree C at 753 mmHg

Density:

Based on available data from various reliable sources such as authoritative database and handbooks, the density of chemical Methyl methanesulfonate was determined to be 1.29 g/cm3 at 20 degree C.

Particle Size Distribution:

The study does not need to be conducted because the test chemical is marketed or used in a non- solid or granular form.Methyl methanesulphonate is a liquid chemical.

Hence, this endpoint can be considered for waiver.

Vapor Pressure:

A study was performed to determine the vapor pressure of methyl methanesulphonate. The vapour pressure of methyl methanesulphonate at 59 degC was determined to be 80Pa.

Data from authoritative and modelling databases suggests that the estimated vapour pressure of Methyl methanesulphonate at 25 degC was 0.310 mmHg = 41.33Pa at 25 deg C

Partition Coefficient:

Based on the available data from authoritative and modelling databases, the partition coefficient (log Pow) value of the substance Methyl methanesulfonate was estimated to be -0.66. On the basis of the estimated value, chemical Methyl methanesulfonate can be considered to be hydrophilic in nature.

Water Solubility:

A study was performed to determine the solubility of Methyl methanesulphonate in water. The water solubility of methyl methanesulphonate at 20°C was determined to be 200000 mg/L .

Data from various authoritative and modelling databases suggests that the estimated water solubility of methyl methanesulphonate at 25 degC was 1000000 mg/l.

The estimated and experimental values indicate that methyl methanesulphonate is highly soluble in water.

Surface tension:

Based on the data from ACD labs, surface tension for Methyl methanesulfonate (66 -27 -3) was predicted to be 33.8 ± 3.0 dyne/cm.

Flash point:

The flash point of the test material methyl methanesulphonate from handbook and database was determined to be 104°C. Based on criteria mentioned in CLP regulation the chemical has flash point >than 60 degree C hence the substance was considered to be non-flammable.

Autoflammability:

Methyl methanesulfonate did not catch fire on being exposed to air at room temperature of 27°Cpressure of 966 hPa. This indicates that Methyl methanesulfonate is not auto-flammable.

Flammability:

Methyl methanesulfonate does not indicate any ignition when the flame of bunsen burner having temperature of approximately 950°C is brought in contact with it. Thus it can be concluded that Methyl methanesulfonate is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus Methyl methanesulfonate was considered non-flammable for chemical safety assessment.

Explosiveness:

The study does not need to be conducted because there are no chemical groups present in the molecule which are associated with explosive properties

Oxidising properties:

The study does not need to be conducted because the inorganic substance does not contain any oxygen or halogen atoms and hence, the classification procedure does not need to be applied.

Additional information

Other supporting studies from various reliable sources such as authoritative database ,review article and handbooks also indicates that the boiling point of  chemical Methyl methanesulfonate was determined to be in the range of 185 degree C to 203 degree C,and the selected key study value lies in the range as mentioned.

Density:

Based on available data from various reliable sources such as authoritative database and handbooks, the density of chemical Methyl methanesulfonate was determined to be 1.29 g/cm3 at 20 degree C.

Other supporting studies from various reliable sources such asauthoritative database and handbook, the density of  chemical Methyl methanesulfonate was determined to be in the range of 1.046 g/cm3 to 1.30 g/cm3 nand the selected key study value lies in the range as mentioned.

Particle Size Distribution:

The study does not need to be conducted because the test chemical is marketed or used in a non- solid or granular form.Methyl methanesulphonate is a liquid chemical.

Hence, this endpoint can be considered for waiver.

Vapor Pressure:

A study was performed to determine the vapor pressure of methyl methanesulphonate. The vapour pressure of methyl methanesulphonate at 59 degC was determined to be 80Pa.

Data from authoritative and modelling databases suggests that the estimated vapour pressure of Methyl methanesulphonate at 25 degC was 0.310 mmHg = 41.33Pa at 25 deg C

Partition Coefficient:

Based on the available data in a key studyfrom authoritative and modelling databases, the partition coefficient (log Pow) value of the substance Methyl methanesulfonate was estimated to be -0.66.

In a supporting study from authoritative database, the partition coefficient (log Pow) value of the substance Methyl methanesulfonate was estimated to be -0.7.

Thus, based on the available information, the logPow valueof the test substance Methyl methanesulfonate ranges from -0.66 to -0.7, respectively. On the basis of this value, chemical Methyl methanesulfonate can be considered to be hydrophilic in nature.
