Frequently Asked Questions
What is 1-hexadecylnaphthalene used for?
It is a long-alkyl-chain aromatic hydrocarbon (a hexadecyl-substituted naphthalene) used as a lubricating agent. It functions as a functional component in lubricant formulations. Supplied as a specialty additive.
What is the molecular formula of 1-hexadecylnaphthalene?
The molecular formula is C26H40 and the CAS number is 56388-47-7. It consists of a naphthalene ring system bearing a C16 hexadecyl chain at the 1-position.
What is naphthalene's role in this material?
The naphthalene ring forms the aromatic core of the molecule, while the long hexadecyl chain provides the alkyl character used in lubricant chemistry. The combination yields a long-alkyl-chain aromatic hydrocarbon distinct from unsubstituted naphthalene (C10H8).
What HS code applies to 1-hexadecylnaphthalene?
It is classified under HS 2902.90 (Cyclic hydrocarbons: Other). Confirm the destination-country tariff classification with your customs broker before shipping.
Can I get a CoA and SDS, and what is the bulk price?
A Certificate of Analysis and Safety Data Sheet are provided with bulk orders. Pricing depends on volume and packaging; submit a bulk RFQ with your required quantity for a current quote.
What is the REACH and TSCA regulatory status of 1-Hexadecylnaphthalene?
1-Hexadecylnaphthalene (CAS 56388-47-7) is subject to U.S. TSCA Inventory requirements; supplying it into the EU requires valid REACH registration ((EC) No 1907/2006). RawSource cannot verify a third-party supplier's registrations — buyers should require documented TSCA and REACH compliance for their jurisdiction and volume.
