As an ester, the compound is going to be somewhat unstable in water, especially at acidic or basic pH. Time, temperature and pH will all influence how much spontaneous hydrolysis will occur. Make the stock solution fresh for each experiment at neutral pH and keep it on ice. If the compound is already yellow when freshly dissolved, you should order a new batch.
