preliminarily study was conducted to determine the MTDID 15670
solubility in n-octanol. Triplicate samples were prepared at a nominal
100 mg/mL of MTDID 15670 in n-octanol in a nominal 1.5 mL polypropylene
centrifuge tube. The samples were incubated in a shaker at 100 RPM and
at average 30±1 °C for approximately 69 hours. Upon removal from the
incubator, the samples were equilibration at ambient temperature for >
24 hours then centrifuged. Triplicate aliquots of each n-octanol sample
were removed, diluted,and
analyzed using LC/MS/MS. MTDID 15670 contains a sulfonium cation and a
tetrafluoroborate anion components. The cation and anion concentration
in octanol were measured independently in each of the samples, and MTDID
15670 concentration in the octanol was determined by summing the
measured cation and anion concentration.The
n-octanol solubilities of cation and anion components of MTDID 15670 at
ambient room temperature (22 ± 2°C) were 5.19 mg/mL (RSD%=15%) and 0.924
mg/mL (RSD%=17%), respectively. The determined MTDID 15670 n-octanol
solubility was 6.12 mg/mL (RSD%=16%).
This is a
non-GLP preliminary study followed general accepted scientific
principles. It is considered reliable with restriction.
