Tris(3,5-di-tert-butyl-4-hydroxybenzyl) isocyanurate is a high molecular weight additive, with low volatility. It is well suited to stabilising polyolefins against degradation caused by long term heat aging. [1] It is an approved food contact material in the US. [2]
CH 3 CH(OH)CH 2 CHO → CH 3 CH=CHCHO + H 2 O. Hydrogenation of 3-hydroxybutanal gives 1,3-butanediol: CH 3 CH(OH)CH 2 CHO + H 2 → CH 3 CH(OH)CH 2 CH 2 OH. This diol is a precursor to 1,3-butadiene, precursor to diverse polymers. Polymerization of 3-hydroxybutanal is also spontaneous, but can be stopped with the addition of water. Aldol has ...
Butyraldehyde, also known as butanal, is an organic compound with the formula CH 3 (CH 2) 2 CHO. This compound is the aldehyde derivative of butane . It is a colorless flammable liquid with an unpleasant smell.

Like 1,4-BD, it also behaves as a prodrug to GHB when taken exogenously. However, as with all aliphatic aldehydes , γ-hydroxybutaldehyde is caustic and is strong-smelling and foul-tasting; thus, actual ingestion of this compound is likely to be unpleasant and result in severe nausea and vomiting .
Skeletal formula of 3-hydroxyisobutyric acid Hydroxybutyric acid is a group of four-carbon organic compounds that have both hydroxyl and carboxylic acid functional groups . [ 1 ] They can be viewed as derivatives of butyric acid .
Pentaerythritol tetrakis(3,5-di-tert-butyl-4-hydroxyhydrocinnamate) is a chemical compound composed of four sterically hindered phenols linked through a pentaerythritol core. It is used as primary antioxidant for stabilizing polymers , particularly polyethylene and polypropylene .
1,2,4-Butanetriol is also used as a precursor for two cholesterol-lowering drugs, Crestor and Zetia, which are derived from D-3,4-dihydroxybutanoic acid, by using 3-hydroxy-gamma-butyrolactone as a chiral synthon [2] [3] It is used as one of the monomers for manufacture of some polyesters and as a solvent.
