[x·sodium, y·lithium, x+y=3] 4-amino-3[[4-[[4-[(2-amino-4-hydroxyphenyl)diazenyl]phenyl]amino]-3-sulfonato phenyl]diazenyl]-5-hydroxy-6-(phenydiazenyl)naphthalene-2,7-disulfonat, mixture of isomers

Flash point

Administrative data

Endpoint:

flash point of flammable liquids

Data waiving:

study technically not feasible

Justification for data waiving:

the study does not need to be conducted because the flash point is only relevant to liquids and low melting point solids

Cross-reference

Reason / purpose for cross-reference:

data waiving: supporting information

Reference

Endpoint:

melting point/freezing point

Type of information:

(Q)SAR

Adequacy of study:

supporting study

Study period:

2018

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

results derived from a valid (Q)SAR model and falling into its applicability domain, with adequate and reliable documentation / justification

Qualifier:

no guideline required

Principles of method if other than guideline:

Calculation of the melting point by EPIWEB

Type of method:

other: calculation

Key result

Melting / freezing pt.:

349.84 °C

Atm. press.:

1 atm

Conclusions:

The calculated melting point of Direct Black RBB is predicted to be ca 350°C
