On the basis of physical observation,the chemical N-(4-((4-(dimethylamino)phenyl)(4-(phenylamino)naphthalen-1-yl)methylene)cyclohexa-2,5-dienylidene)-N-methylmethanaminium acetate was observed to be maroon coloured lustrous liquid in appearance.
Freezing point:
The Freezing point determination of [4-[[4-anilino-1-naphthyl][4- (dimethylamino)phenyl]methylene]cyclohexa-2,5-dien-1-ylidene]dimethylammonium acetate (CAS No.83803-79-6) was done using crushed ice and salt.. No freezing was observed up to - 16.39°C. Hence, the freezing point was inferred to be less than -16.39 °C at 970.2 hPa.
Boiling point:

The test item does not show string of bubbles up to 300 °C.,inferring b.p. to be greater than 300 °C. and boiling point was determined to be greater than 300°C at 968.8 hPa.
Density:
The density of chemical [4-[[4-anilino-1-naphthyl][4- (dimethylamino)phenyl]methylene]cyclohexa-2,5-dien-1-ylidene]dimethylammonium acetate (CAS No. 83803-79-6)was determined following OECD Guideline 109 and according to the IS 4730 : 1994 (Reaffirmed 2010) – Method for Determination of Density of Liquids (First Revision) using glass pyknometer. The mean density of chemical was determined to be 1.1013 g/cm³at 20°C and 971.2 hPa.

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 organic substance contains oxygen or halogen atoms which are chemically bonded only to carbon or hydrogen and hence, the classification procedure does not need to be applied
Stability in organic solvents and identity of relevant degradation products :
The study does not need to be conducted because the stability of the substance is not considered to be critical.
pH :
The pH determination of test item [4-[[4-anilino-1-naphthyl][4-(dimethylamino)phenyl]methylene]cyclohexa- 2,5-dien-1-ylidene]dimethylammonium acetate (CAS No 83803-79-6) was done following OECD guideline 122. pH of 1% w/v emulsion was measured with the help of pH meter and it was observed to be 2.69 at 31°C.
Dissociation constant :
The study does not need to be conducted because the substance is readily oxidisable in water.
Viscosity :
Kinematic viscosity (experimental) of [4 -[[4 -anilino-1 -naphthyl][4 - (dimethylamino)phenyl]methylene]cyclohexa-2,5 -dien-1 -ylidene]dimethylammonium acetate( CAS No.83803 -79 -6)at 20°C and 40°C is 51.8700 mm²/sec and 47.1770 mm²/s, respectively.
Dynamic viscosity (calculated) of [4 -[[4 -anilino-1 -naphthyl][4 -(dimethylamino)phenyl]methylene]cyclohexa-
