Butylated Hydroxytoluene (BHT)

BHT
CAS 128-37-0 · Formula C15H24O · MW 220.35 g/mol

A general-purpose hindered-phenol antioxidant that interrupts radical chain oxidation across fuels, polymers, and oils. It inhibits oxidation in fuels, lubricating and process oils, waxes, synthetic rubbers, and plastics, functions as an anti-skinning agent in paints and inks, and in purified grades serves as a food and animal-feed antioxidant.

Full Description

Butylated Hydroxytoluene (CAS 128-37-0), or BHT, is a hindered-phenol antioxidant. It inhibits oxidation in fuels, lubricating and process oils, waxes, synthetic rubbers, and plastics, functions as an anti-skinning agent in paints and inks, and in purified grades serves as a food and animal-feed antioxidant.

Frequently Asked Questions

What is 2,6-di-tert-butyl-4-methylphenol (BHT) used for?

BHT (CAS 128-37-0, C15H24O) is a hindered-phenol antioxidant. It inhibits oxidation in fuels, lubricating and process oils, waxes, synthetic rubbers, and plastics, acts as an anti-skinning agent in paints and inks, and in purified grades serves as a food and animal-feed antioxidant. RawSource supplies it in bulk to industrial and food formulators.

Is 2,6-di-tert-butyl-4-methylphenol the same as BHT?

Yes. 2,6-Di-tert-butyl-4-methylphenol is the systematic name for BHT (butylated hydroxytoluene), CAS 128-37-0. The hindered phenol structure is what gives it antioxidant function.

How does BHT differ from 2,6-di-tert-butylphenol or methylenebis hindered phenols?

BHT carries a methyl group at the 4-position of a 2,6-di-tert-butylphenol ring, while 2,6-di-tert-butylphenol lacks that para-methyl, and methylenebis(4-methyl-6-tert-butylphenol) is a higher-molecular-weight bisphenol antioxidant. These are distinct CAS items with different volatility and performance; confirm identity by CAS on the CoA.

What grades of BHT are available and what HS code applies?

BHT is offered in industrial/polymer-stabilizer grades and in purified food/feed grades; specify your application so the right grade and CoA are matched. It classifies under HS 2907.19 (monophenols, other). Confirm grade and tariff line when ordering.

How is bulk BHT packaged and quoted?

RawSource supplies BHT in bulk (bags, drums, and supersacks depending on form) to manufacturers. Pricing is volume- and grade-dependent, so request a bulk quote with your target quantity and grade; CoA and SDS accompany each shipment.
