 Applications 

1. Nickel Electroplating Brightening & Stress Control — Watts nickel, sulfamate nickel, decorative and functional nickel deposits: A sulfonimide additive in the same family as saccharin, used to refine grain structure and reduce internal stress in the deposited nickel. Lower stress means the deposit can be built thicker without cracking or peeling, which is exactly what functional and engineering plating needs.

2. Electroforming & Thick Deposit Build — electroformed moulds, screens, printing cylinders, bellows: Where nickel is built to hundreds of microns, internal stress is the limiting factor and the additive package decides whether the shell survives. A sulfonimide-type stress reliever keeps the deposit ductile and dimensionally stable through long plating cycles.

3. Organic Synthesis & Sulfonamide Building Blocks — sulfonimide and sulfonamide intermediates, sulfonyl transfer reactions: A ready-made bis-sulfonylimide framework that can be converted into sulfonamides, sulfonimide salts and related derivatives in a single step. Useful where the target needs two sulfonyl groups on one nitrogen, which is awkward to build by sequential sulfonylation.

4. Strong Organic Acid Catalyst — acid-catalysed esterification, Friedel-Crafts type reactions, polymerisation catalysis: Bis(sulfonyl)imides are strongly acidic for neutral organic molecules, which makes them useful as non-volatile, non-oxidising acid catalysts where sulphuric acid would char the substrate or introduce water.

 Quality Assurance 

Every batch of chemicals leaves our factory with complete laboratory documentation — not a promise, but verifiable test data. From incoming raw material inspection to finished-goods release, each batch is tested against published specifications, and a Certificate of Analysis (COA) accompanies every single shipment. What you order is exactly what we test — and what we ship.

Tested by our in-house ISO 9001:2015 laboratory. Verified independently by third-party labs on request (SGS / BV / Intertek). Traceable from raw material to your warehouse.
