Chemical Products
Selected industrial chemicals and chemical raw materials for international B2B customers.
Vekchem supplies seven industrial chemicals and chemical raw materials to manufacturers, formulators and distributors. The range covers quaternary ammonium salts and a phase-transfer catalyst (TBAB, BKC), bromine chemistry (sodium bromate, sodium bromide), sulfur chemistry (sodium hydrosulfide) and chlorinated or brominated aromatic intermediates (4-chlorobenzyl chloride, 4-bromoaniline hydrochloride).
Every product page states the specification we work to, the packing options and the transport classification. Where a limit is not fixed by the standard grade — a tighter impurity ceiling, a smaller pack — we confirm it in writing rather than quote a figure we cannot hold.
