Abstract: There is disclosed a process for making a mono-lithium salt of 5-sulfoisophthalic acid (LiSIPA) having less than 200 ppm sulfate. The process uses a reaction mixture of acetic acid, water, a lithium cation producing compound, and 5-sulfoisophthalic acid. The reaction mixture is heated to reflux, cooled, filtered and washed to obtain a high quality LiSIPA having less than 200 ppm sulfate. Also disclosed is a high quality mono-lithium salt of 5-sulfoisophthalic acid having less than 200 ppm sulfate.

Abstract: This invention relates to methods for the production of sodium, potassium, rubidium, cesium, magnesium, manganese, cobalt, nickel, aluminum, copper (II) and zinc salts of 5-sulfoisophthalic acid. In addition, this disclosure describes new compositions of matter, specifically, the rubidium, manganese, cobalt, nickel, and copper (II) salts of 5-sulfoisophthalic acid. The method utilizes the addition of metals salts to a crude sulfonation solution of 5-sulfoisophthalic acid.

Abstract: A sulfonate of the formula (I): wherein Q1, Q2, Q3, Q4 and Q5 each independently represents a certain substituent, and A+ represents a counter ion, with the proviso that at least one of Q1, Q2, Q3, Q4 and Q5 is a group of the formula (II) wherein R1 and R2 each independently an alkyl having 1 to 12 carbon atoms or the like; and a chemical amplification type positive resist composition comprising the sulfate of the formula (I) and a resin which contains a structural unit having an acid labile group and which itself is insoluble or poorly soluble in an alkali aqueous solution but becomes soluble in an alkali aqueous solution by the action of an acid.

Abstract: Methods for treating conditions associated with hyperglycemia, especially Type II diabetes, with novel naphthylsulfonic acids and related compounds. These compounds, as single stereoisomers or mixtures of stereoisomers, or their pharmaceutically acceptable salts, are useful in methods of stimulating the kinase activity of the insulin receptor, enhancing the activation of the insulin receptor by insulin, and stimulating the uptake of glucose into cells. A variety of antidiabetic compounds and pharmaceutical compositions comprising the antidiabetic compounds are also disclosed.

Abstract: Compounds of Formula I, and pharmaceutical compositions containing these compounds, activate the insulin receptor kinase, which leads to an increased sensitivity to insulin and an increase in glucose uptake, and are therefore useful for the treatment of animals, especially humans, with hyperglycemia, especially for the treatment of type 2 diabetes. Processes for preparation of the compounds, and their use in assays, are also disclosed.
