Intermediates for organic reactions
Intermediates 2,5-DBETHOXY
ANILINE
0C 2 H 5
Readily soluble in most reaction media; shipped as a free base. Diazotization yields a light sensitive salt. A good starting point for synthesis of naphthol color bases. PHENYL,
NH« N(e«£CH a 0H> 2
DIETHANOLAMINE
A reactive intermediate which may be nitrated, sulfonated or halogenated; couples readily with diazo salts to give dye intermediates. Condenses with aliphatic or aromatic aldehydes. m-TOLYL
N(CH2CH20H)2
DIETHANOLAMINE
This aromatic amine undergoes the same reactions as Phenyl Diethanolamine, but the products have slightly different properties due to the methyl group on the aromatic nucleus. 2,5-DIMETHOXY
PHENYL ETHYL
OCH3
CH,
ANILINE
A convenient and economical starting point for Fast Blue 2R salt and other naphthol color bases. Like 2,5-Diethoxy Aniline, it is readily diazotized to yield light sensitive salts. Shipped as a free base.

Intermediates TECQUINOL® (technical Hydroquinone) Reacts readily with amines; condenses readily with phthalic and other anhydrides. Useful as a polymerization inhibitor for monomers and is a widely used arrestor for peroxide-catalyzed polymerizations. 2,5-DI-TERT-BUTYL
HYDROQUINONE

h ft
L
Insoluble in water and aqueous caustic. A polymerization inhibitor for vinyl-type resin monomers, also an effective antioxidant in vegetable fats and oils, and stabilizer against light deterioration of rubber and synthetic elastomers. TOLUHYDROQUINONE
A promising raw material for organic syntheses undergoing the same reactions as hydroquinone. The presence of the methyl group introduces slight variations in the product properties. Intermediates
H Y D R O Q U I N O N E M O N O M E T H Y L ETHER A stabilizing agent and antioxidant; soluble in various fats and oils. Its stable ether group makes it a promising raw material for drug, cosmetic and dye syntheses. ACETANILIDE
