                                            Note: There can be variations in solubility for the same chemical from different vendors or different batches from the same vendor. The following factors can affect the solubility of the same chemical: solvent used for crystallization, residual solvent content, polymorphism, salt versus free form, degree of hydration, solvent temperature. Please use the solubility data as a reference only. Warming and sonication will facilitate dissolving. Still have questions?
