Administrative data
Link to relevant study record(s)
- Endpoint:
- auto-flammability
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study
- Justification for type of information:
- Experimental test result performed using standard test guidelines
- Qualifier:
- according to guideline
- Guideline:
- other: Lowest temperature determined at which substance vaporizes to form an ignitable mixture in air
- Principles of method if other than guideline:
- Lowest temperature determined at which substance vaporizes to form an ignitable mixture in air
- GLP compliance:
- not specified
- Specific details on test material used for the study:
- - Name of test material: 3-amino-5-hydroxynaphthalene-2,7-disulphonic acid
- IUPAC name: 3-amino-5-hydroxynaphthalene-2,7-disulfonic acid
- Molecular formula: C10H9NO7S2
- Molecular weight: 319.3131 g/mole
- Smiles : c1c2cc(c(cc2c(cc1S(=O)(=O)O)O)N)S(=O)(=O)O
- Inchl: 1S/C10H9NO7S2/c11-8-4-7-5(2-10(8)20(16,17)18)1-6(3-9(7)12)19(13,14)15/h1-4,12H,11H2,(H,13,14,15)(H,16,17,18)
- Substance type: Organic
- Physical state: Solid (Light grey, to, Off-white) powder - Key result
- Remarks on result:
- other: 3-amino-5-hydroxynaphthalene-2,7-disulphonic acid ignites only when the flame of bunsen burner having temperature of 950°C is brought in contact with it.Thus it can be concluded that substance is flammable only at high temperature of about 950°C.
- Conclusions:
- 3-amino-5-hydroxynaphthalene-2,7-disulphonic acid did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that 3-amino-5-hydroxynaphthalene-2,7-disulphonic acid is not auto-flammable.
- Executive summary:
3-amino-5-hydroxynaphthalene-2,7-disulphonic acid did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that 3-amino-5-hydroxynaphthalene-2,7-disulphonic acid is not auto-flammable.
