Trichloroisocyanuric Acid 90% (TCCA)

Trichloroisocyanuric Acid 90% (TCCA) (CAS 87-90-1, molecular formula C3Cl3N3O3) is a treatment chemical specified by municipal and industrial plant operators where dose consistency and impurity control directly affect finished water quality. China Chemicals supplies it at 90% available chlorine in pack sizes from 1 kg through to 500 kg Pallet, so laboratory trial quantities and full production volumes can be sourced from the same specification.

It is also traded as TCCA, Symclosene, Trichlor. Every consignment ships with a batch-specific Certificate of Analysis and the current Safety Data Sheet, and material is stored and picked under stock rotation so you receive product well inside its shelf life.
