Profile: AmChemteq Inc. specializes in the development of solid phase extraction (SPE) products for the pharmaceutical and environmental industries. We develop new extraction process of compounds depending on the needs of industries. We can synthesize small amounts of highly pure chemicals for use as analytical standards or drug impurity profiles. We offer a large selection of column packing materials. We provide various high purity chemicals including dibromofluoromethane, 4,4?-nitrodiphenylamine, chloroprene, bromodichloroacetic acid, bromodichloroacetic acid methyl ester, dibenzo(a,i)pyrene, benzo(a)pyrene and dibenz(a,j)acridine. We offer various dinitrophenyl hydrazone derivatives including formaldehyde, acetaldehyde, acetone, acrolein, propionaldehyde, methacrolein, methylisobutylketone, crotonaldehyde, isobutyraldehyde and benzaldehyde-DNPH. We supply custom-made functionalized silica gel, bare silica & silica material for HPLC, SPE, and combinatorial chemistry applications.
