Methylparaben and Propylparaben Melting Point Analysis

Laboratory Test Request Description

Materials Laboratory needed to perform a Melting Point analysis on Methylparaben and Propylparaben.The Method of Analysis is as follows:Dissolve 500 mg of sample in 10 mL of 1 N sodium hydroxide, boil for 30 min, allow the solution to evaporate to a volume of about 5 mL, and cool. Acidify the solution with 2 N sulfuric acid, collect the crystals on a filter, wash several times with small portions of water, and dry in a desiccator over silica gel. The p-hydroxybenzoic acid so obtained melts between 212C and 217C.   The materials that we are trying to obtain the results of are:Methylparaben and Propylparaben Please let me know the cost and required sample size.Thank you !
