Fluorene (CAS: 86-73-7) is a tricyclic aromatic hydrocarbon from coal tar, supplied as white crystalline flakes with a faint violet fluorescence. The reactive methylene bridge at the 9-position allows easy substitution, making it a valuable building block for resins, pharmaceuticals and optoelectronic materials. It is used to prepare fluorenone, bisphenol fluorene and polyfluorene-type materials. It
4-(Diethylamino)salicylaldehyde is a substituted benzaldehyde carrying a hydroxyl group at the 2-position and a diethylamino group at the 4-position, supplied as a yellow to orange crystalline powder at 98% purity. This arrangement of donor and acceptor groups on one benzene ring creates a push-pull chromophore, so the compound is strongly coloured, strongly fluorescent after derivatisation,

Nonylphenol (CAS: 25154-52-3) is a mixture of nonyl-substituted phenol isomers, normally branched, supplied as a pale yellow viscous liquid. It is the usual starting material for nonylphenol ethoxylates, phenolic resins and lubricant additives. Because of environmental restrictions in some regions, buyers should confirm local regulatory status before purchase. It should be stored closed, away from
Ciclopirox olamine is the ethanolamine salt of ciclopirox, a hydroxypyridinone antifungal, supplied as a white to off-white crystalline powder at 99% purity. The salt form greatly improves water solubility compared with the free acid, so the active can be formulated into creams, lotions, gels and shampoos, while the hydroxypyridinone ring chelates polyvalent cations such as

2-Butanol (CAS: 78-92-2) is a secondary four-carbon alcohol supplied as a colorless liquid with a characteristic odor. It is miscible with many organic solvents and moderately soluble in water. It is widely used as an industrial solvent, as a raw material for methyl ethyl ketone (MEK) and as an intermediate for esters and plasticisers. Buyers
Solvent Violet 13 (CAS: 81-48-1) is an anthraquinone dye that dissolves in organic solvents and plastics, giving a clean bluish-violet shade with excellent lightfastness and heat stability. It is widely used to colour plastics, synthetic fibres, waxes, oils, inks and cosmetics as the colorant also known as D&C Violet 2. Its solubility in non-polar media
Acenaphthene (CAS: 83-32-9) is a polycyclic aromatic hydrocarbon in which an ethylene bridge links the 1 and 8 positions of naphthalene. It is supplied as white to pale yellow crystals. It is isolated from coal tar and is a raw material for dyes, pigments, plastics and agrochemicals. Buyers specify high purity and low colour because
N-Benzyl-N-ethyl-m-toluidine is a tertiary aromatic amine with a benzyl group and an ethyl group on the nitrogen, supplied as a pale yellow to brown clear liquid at 98% purity. The molecule is fully alkylated, so it carries no reactive N-H bond and behaves as an electron-rich but chemically stable amine that dissolves readily in aromatic

PTCDA (CAS: 128-69-8), perylene-3,4,9,10-tetracarboxylic dianhydride, is a planar aromatic dianhydride that serves as the parent for perylene pigments and organic electronic materials. It forms highly ordered thin films, strong light absorption and good electron-transport behaviour, and it is very stable to heat and light. It is therefore used for perylene diimide dyes and in organic
N-Ethyl-N-cyanoethyl-m-toluidine is a tertiary aromatic amine bearing an ethyl group and a propionitrile chain on nitrogen, supplied as a colourless to pale yellow clear liquid at 98% purity. The nitrile group is a masked functional handle that can be hydrolysed to an acid, reduced to an amine or cyclised, while the N-ethyl-m-toluidine core provides the

N-(2-Cyanoethyl)-N-ethylaniline is a tertiary aromatic amine with an ethyl group and a propionitrile chain attached to the nitrogen, supplied as a colourless to yellow clear liquid at 98% purity. The propionitrile arm is the reactive feature: under acid or base conditions it cyclises or hydrolyses, converting the simple aniline into fused heterocycles or carboxylic acid

3,3-Dimethylacryloyl chloride is the acid chloride of 3-methyl-2-butenoic acid, supplied as a colourless to pale yellow clear liquid at 98% purity. The molecule contains both a highly electrophilic acyl chloride and an activated, trisubstituted double bond, which makes it a compact bifunctional reagent for introducing the 3-methyl-2-butenoyl (senecioyl) group. Acylation reactions proceed rapidly under mild
