para-tert-Butylphenol is a alkylphenol synthesis intermediate — a building block used in the manufacture of para-tert-butylphenol formaldehyde resins (adhesives, tackifiers), antioxidants, a polycarbonate chain terminator, and fragrance intermediates. Identity: CAS 98-54-4.
What it is
para-tert-Butylphenol (CAS 98-54-4, C10H14O) is a alkylphenol sold as a synthesis intermediate — a defined building block that downstream manufacturers convert into finished products. PTBP is a large-volume alkylphenol intermediate.
Role in synthesis
The phenol reacts with formaldehyde to form resins, can be alkoxylated, and acts as a chain terminator; the tert-butyl group blocks the para position. The substitution pattern (isomer) is part of the identity — confirm the CAS to be sure the isomer matches your route, because position isomers react differently and lead to different products.
What it is used to make
It is a building block toward para-tert-butylphenol formaldehyde resins (adhesives, tackifiers), antioxidants, a polycarbonate chain terminator, and fragrance intermediates. RawSource supplies the intermediate; the downstream synthesis, product registration and any application or efficacy are the responsibility of the manufacturer that uses it.
Forms, grades and handling
Supplied to a defined assay with a Certificate of Analysis (CoA) per lot; define the assay and key impurity limits your route needs. Several halo-aromatic intermediates are hazardous and some are regulated — confirm regulatory status and handling for your jurisdiction, and always consult the current Safety Data Sheet (SDS). Typical values are not a guaranteed specification; the CoA governs.
Bulk and custom-quantity supply
RawSource sources para-tert-Butylphenol direct from producers in bulk and custom quantities, with CoA, TDS and SDS per lot. Tell us the assay and impurity limits and your sample/pilot/production quantity, and we will quote it and confirm supply continuity. See the full range in the intermediates guide.
