Chemical Products

2-Ethylhexyl Thioglycolate (CAS: 7659-86-1) is a mercapto ester supplied as a colourless clear liquid with a mild, sulfurous odour. It combines a branched, hydrophobic 2-ethylhexyl group with a reactive thiol, making it soluble in hydrocarbon and plasticiser systems and readily available for addition or transesterification chemistry. Commercial assay is 99% with low free acidity and

Isobutyraldehyde (CAS: 78-84-2) is a branched aliphatic aldehyde supplied as a colourless clear liquid with a pungent, fruity odour. The single alpha-branch makes the aldehyde sterically hindered yet reactive, so it undergoes aldol condensation, hydrogenation, oxidation and reductive amination to give neopentyl-type diols, isobutyric acid and branched amines. Bulk material is 99% with controlled isomer

Methanesulfonic Anhydride (CAS: 7143-01-3) is the anhydride of methanesulfonic acid, supplied as a white to pale yellow crystalline solid with a pungent odour. It transfers the mesyl group rapidly to alcohols, phenols and amines, giving mesylate esters that are excellent leaving groups, and it is often preferred to mesyl chloride where chloride introduction or acidic

2,3,5,6-Tetrafluoroterephthalic Acid (CAS: 652-36-8) is a fluorinated dicarboxylic acid supplied as a white crystalline powder. The four ring fluorines lower polarizability and increase chemical and thermal resistance while the two para carboxyl groups allow polycondensation, so the compound behaves as a fluorinated analogue of terephthalic acid. Commercial assay is 98% with controlled inorganic content, and

Diketene (CAS: 674-82-8) is a cyclic dimer of ketene supplied as a colourless clear, mobile liquid with a sharp, irritating odour. The strained four-membered lactone ring opens readily with nucleophiles, so the molecule acts as an acetoacetylating agent and as a convenient, transportable source of ketene chemistry for building acetoacetamides, pyrazolones and heterocycles. Commercial material

N-Methyl-p-toluidine (CAS: 623-08-5) is a secondary aromatic amine supplied as a colourless to pale yellow clear liquid that darkens gradually on exposure to light and air. The N-methyl group increases basicity and reactivity in electrophilic substitution, so the ring is readily nitrosated, sulfonated or coupled, while the para methyl group blocks one position and directs

Ethyl 3-Aminocrotonate (CAS: 626-34-6) is an enamine ester supplied as a pale yellow clear liquid that may solidify at low temperature. The molecule combines a nucleophilic amino group with an electrophilic ester on an activated double bond, so it undergoes condensation with carbonyls, amidines and hydrazines to close five- and six-membered nitrogen heterocycles in a

1-Bromoheptane (CAS: 629-04-9) is a straight-chain primary alkyl bromide supplied as a colourless clear liquid with a faint, characteristic odour. The primary bromide is an efficient substrate for SN2 displacement, so it is used to attach a linear seven-carbon chain to amines, phenols, thiols, carboxylates and heterocyclic nitrogens. Commercial assay is 99% with low free

Pivalonitrile (CAS: 630-18-2) is a branched aliphatic nitrile supplied as a colourless clear liquid with a mild, ethereal odour. The bulky tert-butyl group shields the nitrile carbon, so the compound is a useful source of the tert-butyl motif and can be hydrolysed to pivalamide, reduced to neopentylamine derivatives or used as a polar aprotic co-solvent.

4-Nitrobenzoic Acid (CAS: 62-23-7) is an aromatic carboxylic acid supplied as a white to pale yellow crystalline powder. The para-nitro group withdraws electron density, which activates the ring towards nucleophilic substitution and strengthens the acidity of the carboxyl group, so the compound is a useful substrate for reduction to 4-aminobenzoic acid and for esterification studies.

3-Methylbenzaldehyde (CAS: 620-23-5) is an aromatic aldehyde carrying a methyl group at the meta position, supplied as a colourless to pale yellow clear liquid with a sweet, almond-like odour. The aldehyde group is reactive towards condensation, reductive amination and oxidation, while the meta methyl group directs further substitution and slightly modifies the odour profile compared
