Full Description

Naphthalene sulfonate (sodium naphthalene-1-sulfonate, CAS 130-14-3) is the sodium salt of a sulfonated naphthalene. Established uses include service as a chemical intermediate for alpha-naphthol and naphthol derivatives and as a sulfonate used to render phenols water-soluble.

Frequently Asked Questions

What is naphthalene sulfonate used for?

Sodium naphthalene sulfonate (CAS 130-14-3) is used primarily as a chemical intermediate — a precursor for alpha-naphthol and naphthol derivatives — and as a sulfonated-naphthalene building block in dye-intermediate synthesis. It is also used as a solubilizing aid to render phenols water-soluble. RawSource supplies it in bulk to manufacturers and formulators.

What is the other name for sodium naphthalene sulfonate?

It is also known as sodium naphthalene-1-sulfonate, the sodium salt of naphthalenesulfonic acid. The reference identifier for procurement is CAS 130-14-3, molecular formula C10H7NaO3S.

What is naphthalenesulfonic acid used for?

Naphthalenesulfonic acid is the parent acid of this sodium salt and serves as a sulfonated-naphthalene intermediate in dye and naphthol-derivative chemistry. The sodium sulfonate form supplied here is the salt of that acid, used for the same intermediate and solubilizing functions.

What is the HS code for sodium naphthalene sulfonate?

It classifies under HS 2904.10 — derivatives of hydrocarbons containing only sulfo groups, their salts and ethyl esters. Confirm the importing-country tariff line against your own customs broker; RawSource provides commercial documentation with each bulk shipment.

What is the cost of bulk naphthalene sulfonate?

Bulk pricing depends on grade, packaging, and order volume. Request a current quote from RawSource with your target quantity and packaging (drums, totes, or bags) for landed pricing and a CoA/SDS.
