 Applications 

1. For Electroplating And Metal Finishing: Methane disulphonic acid sodium salt (methanedisulfonic acid disodium salt, CAS 5799-70-2) is used as an electroplating additive in tin and tin-alloy plating formulations, helping improve deposit uniformity, surface smoothness and brightness while supporting stable operation of matte and bright tin plating baths.

2. For Electronics And Industrial Tin Plating: In plating lines for electronic and industrial components, this sulfonate salt supports consistent coating quality in tin and solderable finishes, where uniform leveling and reproducible deposit performance are critical for downstream assembly and reliability.

3. For Organic Reactions And Catalysis: As part of the methane sulfonate chemical family, the compound serves as a catalyst source in organic reactions such as esterification and condensation, giving process chemists a stable salt form that is easier to handle than the corresponding acid.

4. For Fine Chemical Synthesis: The sodium salt acts as a versatile raw material for preparing methanedisulfonic acid and downstream sulfonate derivatives, supporting the manufacture of specialty additives and functional chemicals for industrial applications.

5. Reliable Supply For Industrial Customers: Offered in high-purity industrial grade with consistent assay, this additive gives electroplating and chemical manufacturers a dependable, cost-effective raw material with flexible packaging, stable supply and professional technical support.

 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.
