2-Aminophenol (o-Aminophenol; CI 76520) and its salts
The invention also concerns novel 3-aminophenol derivatives.
A substrate when cleaved preferably leads to a p-aminophenol.
This resorcinol and m-aminophenol derivative blend can be prepared by melt blending of resorcinol with one or more derivative of m-aminophenol compound.
Propylene oxide and m-aminophenol are the preferred reactants.
The anti-inflammatory agent comprises 2-aminophenol or a derivative thereof as an active ingredient.
Number two worldwide in para-aminophenol and number three in paracetamol in Europe.
The epoxy resin system contains a tertiary amine catalyst such as a tertiaryaminophenol, a benzyl tertiary amine or an imidazole compound.
Then meta-aminophenol is subjected to carboxylation in PASK by the Kolbe-Schmitt reaction.
Sometimes, it is shortened to APAP, for N-acetyl-para-aminophenol.

Acetanilide and derivatives (except N-Acetyl-ρ-amino phenol)
The present invention relates to the use of a bi-functional catalyst for the one-step preparation of para-am inophenol, said catalyst comprising a mixture of a hydrogenation noble metal and a zirconium sulfate.
These new enzymatic amplification systems may be used for very sensitive p-aminophenol detection assays and for enzyme immunoassays.
In general, the present invention provides a reliable assay for the quantitative determination of p-aminophenol in an aqueous sample.
At first, resorcinol is affected by ammonia (NH3), which makes it possible to obtain meta-aminophenol.
The product contains too much p-aminophenol (measured value: 7.2% in weight) and insufficient coupling agent.
Then meta-aminophenol is subjected to carboxylation in PASK by the Kolbe-Schmitt reaction.
The present invention relates to means for colouring keratinic fibres which contain 4-amino-2-((diethylamino)methyl)phenol as developing component and 2-methyl-5-aminophenol as coupling component.
Paracetamol is also referred to chemically as N-acetyl-para-aminophenol (abbreviated to: APAP), 4'-hydroxyacetanilide or 4-acetamidophenol.

Number two worldwide in para-aminophenol and number three in paracetamol in Europe.
Taixing is one of the leading Chinese producers of para-aminophenol (“PAP”), a chemical intermediate mainly used for the production of paracetamol.
Preferred functional groups include those derived from adhesion promoters (e.g., 2-aminophenol), photoinitiators (e.g., 4-aminoacetophenone), and solubilizers (e.g., 4-aminobenzoic acid).
These systems are characterized in that p-aminophenol is present as mediator and oligosaccharide dehydrogenase or NADH-independent glucose dehydrogenase (EC 1.1.99.17) is present as mediator-reducing enzyme.
