OPA assay: When o-Phthlaldehyde (OPA) bonds to primary amine
groups within an aqueous solution it gains the ability to fluoresce.
DKP is formed through the intramolecular reaction of the primary amine
with the methyl ester group of aspartame.
The antiepileptic drug (AED) vigabatrin, a [gamma]-vinyl analog of the neurotransmitter GABA, appeared the most likely interfering compound because of the presence of a free primary amine
and a carboxylic acid within its chemical structure that ninhydrin might label analogously to amino acids.
6 times faster with phenyl glycidyl ether (PGE) than the primary amine
Angus Chemical Company, a wholly owned subsidiary of the Dow Chemical Company, introduced an enhanced primary amine
, the AEPD VOX 1000 Multifunctional, for interior water-based paints to the Asia Pacific paint and coatings market during the Asia Pacific Coatings Show in late June.
Lord Corporation has received a patent for an ambient temperature curable coating composition in a mixture of two-parts providing a nonvolatiles content of from 4-25% by weight, and comprised of a part A which is comprised of an organic solvent and fluoroelastomer dissolved therein, the fluoroelastomer containing crosslinkable sites in quantitative amount according to an acid number of from 2-6 mg base per gram, and a part B comprised of an organosilane comprising hydrolyzable groups and a mono primary amine
, wherein the ratio of amine equivalents in part B to acid equivalents in part the A ranges from 3:1 to 12:1 and wherein a cured unsupported film from the coating exhibits at least 200% elongation.

In this article, to investigate a redox initiation system consisting of oil-soluble components, ATP was firstly modified to bear primary amine
groups, and then a Schiff Base reaction was employed to anchor aromatic tertiary amine groups on the surface of ATP.
The two monoprimary amines--n-amyl and n-dodecyl amine--effect chain extension by simply joining two epoxy resin molecules via the single difunctional primary amine
