Product Description

Structural Formula:

Trichloroisocyanuric Acid (TCCA)

CAS NO. 87-90-1
HS NO:2933.6922
Molecular formula: C3N3O3Cl3
Molecular weight: 232.44

Properties:

TCCA is usually sold in solid granular form which can be an economical choice when compared to liquid alternatives. In addition to being an easy-to-use sanitizer that delivers fast results with minimal effort, its effectiveness continues even when mixed with dust and dirt particles.

TCCA is also very soluble in water which makes it an ideal option for use in water tanks and pools while still being able to provide quick disinfection without leaving any irritating residues on surfaces or fabrics. Furthermore, it does not corrode metals or other materials like many other sanitizers do which makes it a great choice for long-term use.

Applications

TCCA is suitable for use both indoors and outdoors due to its versatility and user-friendly features. It can be used on hard surfaces such as kitchen countertops or floors as well as on soft surfaces like sheets and towels without causing any damage or discoloration. It can also be used on laundry machines and dishwashers after each cycle to keep them germ-free.

In terms of water sanitation applications, this compound can be used in swimming pools and aquariums to ensure good quality of the water while keeping algae blooms at bay. It is also widely used for disinfecting drinking water tanks since it does not affect the pH balance of the water nor does it leave any irritating residuum behind like some other products may do.

TCCA — Frequently Asked Questions (FAQ)

What is Trichloroisocyanuric Acid (TCCA) used for?

TCCA is a high-efficiency chlorine disinfectant and algaecide with about 90% available chlorine. It is used for swimming-pool and drinking-water disinfection, cooling-water microbial control, industrial bleaching and sanitation. It is supplied as granules, powder or tablets.

What is the recommended dosage of TCCA?

For pool disinfection TCCA is dosed to maintain about 1–3 ppm free available chlorine; for cooling-water microbial control it is shock- or slug-dosed according to the microbiological load.

What is the difference between TCCA and SDIC?

TCCA and SDIC are both chlorinated isocyanurate disinfectants. TCCA has higher available chlorine (about 90%) and slow dissolution, ideal for stabilized, sustained chlorination (tablets). SDIC (about 56–60%) dissolves quickly at near-neutral pH, ideal for fast or emergency disinfection.

What should I include in a Trichloroisocyanuric Acid (TCCA) enquiry?

For microbiological-control candidate selection, include open or closed system and intended use; planktonic versus attached-growth evidence; ph, temperature, demand and contact conditions; materials, other chemicals and local requirements. State the proposed grade or specification, quantity, packaging and destination so the product and commercial requirements can be compared.
