Obseravtionn Table:

Sample stirring	Concentration obtained on the basis of standard curve	Dilution factor	Solubility value obtained (mg/L)
24 hour	19.1543 mg/L	200	3830.86 mg/L
48 hour	22.2111 mg/L	200	4442.22 mg/L
72 hour	25.2928 mg/L	200	5058.56 mg/L

Considering the water solubility for 48 hrs and 72 hrs the mean water solubility was calculated as follows:
Mean water solubility value for 48 hour run sample + 72 hour run sample
=(4442.22+5058.56)/2
=4750.39 mg/L

Conclusions:

The water solubility determination of test item 3-[(4,5-dihydro-3-methyl-5-oxo-1-phenyl-1H-pyrazol-4-yl)azo]-N,N,N-trimethylanilinium chloride(CAS No.68391-31-1) was done as per the OECD guideline 105 by spectrophotometric analytical method as per OECD 101. The solubility of in water was determine to be 4750.39 mg/L at 28°C.
Thus the test chemical 3-[(4,5-dihydro-3-methyl-5-oxo-1-phenyl-1H-pyrazol-4-yl)azo]-N,N,N-trimethylanilinium chloride(CAS No.68391-31-1) is considered to be soluble in water.

Executive summary:

The water solubility determination of test item 3-[(4,5-dihydro-3-methyl-5-oxo-1-phenyl-1H-pyrazol-4-yl)azo]-N,N,N-trimethylanilinium chloride(CAS No.68391-31-1) was done as per the OECD guideline 105 by spectrophotometric analytical method as per OECD 101.
