According to the CLP Regulation (EC) No 1272/2008, Section 2.1.1.2., an explosive substance or mixture is a solid or liquid substance or mixture of substances which is in itself capable by chemical reaction of producing gas at such a temperature and pressure and at such a speed as to cause damage to the surroundings.

 

A screening procedure has been used to assess the explosive properties of2-propen-1-amine, N-2-propen-1-yl, hydrochloride.This has taken into consideration the following:

 

1. Annex VII of the REACH regulation ((EC) No 1907/2006), section 7.11, which states that a study of the explosive properties of a substance need not be conducted if ‘there are no chemical groups associated with explosive properties present in the molecule’.
2. Section 2.1.4.3 of the CLP regulation covering explosive properties states that a substance or mixture shall not be classified as explosive if:

a.    There are no chemical groups associated with explosive properties present in the molecule. Example of groups which may indicate explosive properties are given in Table A6.1 in Appendix 6 of the UN Recommendations on the Transport of Dangerous Goods, Manual of Test and Criteria; or

b.    The substance contains chemical groups associated with explosive properties which include oxygen and the calculated oxygen balance is less than – 200.

 

 

c.    When the organic substance or a homogeneous mixture of organic substances contains chemical groups associated with explosive properties but the exothermic decomposition energy is less than 500 J/g and the onset of exothermic decomposition is below 500°C. The exothermic decomposition energy can be determined using a suitable calorimetric technique.

d.      For mixtures of inorganic oxidising substances with organic material(s), the concentration of the inorganic oxidising substance is:

i.        Less than 15 % by mass, if the oxidising substance is assigned to Categories 1 or 2;

ii.      Less than 30 % by mass, if the oxidising substance is assigned to Category 3.

 

An evaluation of the functionality within the substance has been performed to identify the presence of elements commonly associated with explosive properties as described inTable A6.1 in Appendix 6 of the UN Recommendations on the Transport of Dangerous Goods, Manual of Test and Criteria.

 

Functional Group (examples)	Comments/Conclusions
C-C unsaturation (acetylenes, acetylides, 1,2-dienes)	Contains two C=C bonds but are not in conjugation.
C-Metal and N-Metal (Grignard reagents, organo-lithium compounds)	Not present
Contiguous N atoms (azides, aliphatic azo compounds, diazonium salts, hydrazines	Not present
Contiguous O atoms (peroxides, ozonides)	Not present
N-O (hydroxylamines, nitrates, nitro compounds, nitroso compounds, N-oxides)	Not present
N-Halogen (chloramines, fluoroamines)	Not present
O-Halogen (chlorates, perchlorates)	Not present

 

The raw materials used to manufacture the substance contain halogen and nitrogen, and while these elements are present in the final product, they are not associated with the functional groups with explosive properties. The substance contains C-C unsaturation, however, these double bonds are not in functional groups associated with explosive properties. Furthermore, the substance is provided as an aqueous solution and therefore would be unlikely to have explosive properties.

Interpretation of results:

GHS criteria not met

Conclusions:

2-propen-1-amine, N-2-propenyl-, hydrochloride does not have explosive properties and does not require classification for explosive properties.

Executive summary:

2 -propen-1 -amine, N-2 -propenyl-, hydrochloride has been assessed for explosive properties. The assessment is based on examination of the functionality within the substance. It was concluded that 2 -propen-1 -amine, N-2 -propenyl, hydrochloride has a calculated oxygen balance of less than 200, does not have explosive properties and does not require classification for explosive properties.
