Used as a catalyst and acid scavenger in organic synthesis, particularly in the production of pharmaceuticals, agrochemicals, and dyes. Commonly employed in the manufacture of esters, amides, and other derivatives by neutralizing acids formed during reactions. Widely utilized in the preparation of polymers and resins as a curing agent or catalyst. Also serves as a mobile phase additive in chromatography for the analysis of basic compounds. Its volatility and basicity make it suitable for use in analytical chemistry and as a reagent in titrations. Frequently used in quality control laboratories as a reference standard for testing purity and performance in various analytical methods.
