Administrative data
Description of key information
Appearance/physical state / colour
On the basis of physical observation and using the sense of smell, test chemical was observed to be clear colourless to pale yellow liquid .
Melting point / freezing point
The freezing point of test chemical was determined as per OECD 102 adopted 27.07.95 using Micro LAB interface FS-524 data generating system and thermostat as temperature detecting system . Freezing Point of test chemical was observed to be less than -13.2 °C at 968.5 hPa.
Boiling point
The boiling point determination of was done as per the test guideline OECD 103. The method followed was according to Siwoloboff. The boiling point of test chemical is 181.3°C at 971.1 hPa
Density
The Log Pow value was determined using Reverse Phase High Performance Liquid Chromatography (RP-HPLC) method according to OECD Guideline No. 117 Adopted: 13 April 2004 and was determined to be 3.692 at 25 deg c.
Water solubility
The water solubility determination of test item was done as per the OECD guideline 105 by spectrophotometric analytical method as per OECD 101. The solubility of test chemical in water was determine to be 30.59 mg/L at 25°C.
Thus the test chemical is considered to be slightly soluble in water.
Surface Tension
The surface tension of test substance is determined to be 25.35dynes/cm at 20 °C and 969.6 hPa.
Flash point
The flash point determination of test chemical was done . The method is closed cup method using Abel's Flash Point Apparatus. The flashpoint of the test chemical was determined to be 57.6°C at 972.6 hPa
Auto flammability
Test chemical did not catch fire on being exposed to air at room temperature of 28°C and pressure of 975 hPa. This indicates that the test chemical is not auto-flammable.
Flammability
Flash point of test substance was determined to be 57.6°C at 972.6 hPa. On the basis of GHS classification criteria, test chemical has flash point ≥ 23°C to < 60°C hence the test chemical was considered to be flammable and considered to be classified as flammable liquid category 3.
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 there are no chemical groups present in the molecule which are associated with oxidising properties and hence, the classification procedure does not need to be applied
pH
The pH of test substance is 6.47 at 20.7 deg C
Additional information
Appearance/physical state / colour
On the basis of physical observation and using the sense of smell, test chemical was observed to be clear colourless to pale yellow liquid .
Melting point / freezing point
Modified Grain method (Mean of Antoine and Modified Grain methods) was used to estimate the vapour pressure of the test substance using MPBPVP v1.43 of EPI SUITE.
The estimated vapour pressure of the test substance at 25deg C was 277 Pa which is 2.08 mmHg .
Partition coefficient
The study was conducted to determine the solubility of test chemical in ultra-pure water, according to the OECD guideline 105 (Adopted by the Council on 27th July 1995) and OECD 101(Adopted: 12 May 1981). Test was conducted at 25±2 °C in two stages; preliminary test for 24 h, followed by confirmatory test for 24 h, 48 h and 72 h in replicates. The final water solubility value was calculated based on average of the individual values obtained after 24 h, 48 h and 72 h. The difference between the average values in three vessels was not observed more than 15%. The water solubility value was observed to be 30.59 mg/L at 25±2 °C.
Thus the test chemical was considered to be slightly soluble in water .
Surface Tension
A study was performed to determine the surface tension of 7-Bromo-1-heptene (CAS NO. 4117-09-3) at atmospheric pressure. Thestudy was conducted in accordance with ISO 9101:1987 Surface active agents: Determination of interfacial tension -Drop volumemethod. The mean surface tension was determined to be 25.35dynes/cm at 20 °C and 969.9 hPa
Flash point
Test chemical did not catch fire on being exposed to air at room temperature of 28°C and pressure of 975 hPa. This indicates that the test chemical is not auto-flammable.
Flammability
Flash point of test substance was determined to be 57.6°C at 972.6 hPa. On the basis of GHS classification criteria, test chemical has flash point ≥ 23°C to < 60°C hence the test chemical was considered to be flammable and considered to be classified as flammable liquid category 3.
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 there are no chemical groups present in the molecule which are associated with oxidising properties and hence, the classification procedure does not need to be applied
pH
Based on experimental data performed according to OECD 122 ,pH value for 1% aqueous emulsion of test substance was observed to be 6.47 at 20.7 °C ,inferring that substance is acidic in nature.
