3-Methylsalicylic Acid (CAS: 83-40-9) is a substituted salicylic acid supplied as a white to off-white crystalline powder. The hydroxyl group sits ortho to the carboxyl, while the methyl group occupies the remaining ring position, so the compound is ready for diazotisation-free coupling reactions and for chelation chemistry with metal ions. Commercial assay is 99% with

Alogliptin Intermediate (CAS: 865758-96-9) is a chlorinated pyrimidinedione bearing an ortho-cyanobenzyl group, supplied as a white to off-white crystalline powder. The ortho-nitrile is ideally positioned to cyclise onto an amine of the aminopiperidine partner, closing the pyrimidinedione ring of alogliptin in the final steps of synthesis. Commercial assay is 98% with controlled single chlorinated impurity,

Oxalyl Chloride (CAS: 79-37-8) is a low-molecular-weight diacid chloride supplied as a colourless to pale yellow clear liquid with a sharp, irritating odour. It is a powerful chlorinating and formylating reagent, widely used to convert carboxylic acids to acid chlorides under mild conditions, for Swern oxidations and for introducing oxalyl or formyl groups into aromatic
Diammonium Glycyrrhizinate (CAS: 79165-06-3) is a licorice-derived sweetener and anti-inflammatory supplied as a white to pale yellow powder, freely soluble in water. It is the diammonium salt of glycyrrhizic acid, roughly fifty times sweeter than sucrose with a lingering licorice note, and it is used to mask bitterness, improve mouthfeel and reduce irritation in food,

Loxoprofen Sodium (CAS: 80382-23-6) is a nonsteroidal anti-inflammatory active pharmaceutical ingredient, supplied as a white to off-white crystalline powder that is soluble in water. It is a prodrug that is converted to its active trans-alcohol metabolite, blocking cyclooxygenase and reducing prostaglandin synthesis, and it is used for musculoskeletal pain, post-operative inflammation and fever. Pharmacopoeial material
Halquinol (CAS 8067-69-4) is a mixture of chlorinated 8-hydroxyquinolines obtained by chlorinating 8-quinolinol. Common components include 5-chloro-8-quinolinol, 5,7-dichloro-8-quinolinol, 7-chloro-8-quinolinol and 8-hydroxyquinoline. Individual components are represented by C₉H₅ClNOR; the mixture composition is variable and specified by total quinoline content.
4-(Chloromethyl)-5-methyl-1,3-dioxol-2-one (CAS: 80841-78-7), commonly called DMDO-Cl, is a cyclic carbonate supplied as a colourless to light yellow clear liquid. The two functional handles allow sequential substitution and esterification, and the dioxolone ring is designed to release the prodrug moiety after hydrolysis, which makes the compound a key intermediate for medoxomil-type pharmaceuticals. Commercial assay is 98%

Bromoacetic Acid (CAS: 79-08-3) is a halogenated carboxylic acid supplied as a white to off-white crystalline solid. The bromine alpha to the carboxyl group is highly reactive, so the compound is used for carboxymethylation of amines, thiols and phenols and for building substituted acetic acid frameworks; it is also a classic intermediate for thioglycolic acid.
4-Amino-5-(ethylsulfonyl)-2-methoxybenzoic Acid (CAS: 71675-87-1) is an aromatic acid bearing amino, methoxy and ethylsulfonyl substituents, supplied as a white to off-white crystalline powder. The ready-made substitution pattern makes it the direct precursor to the benzamide portion of amisulpride, since the carboxyl group can be coupled with an aminomethylpyrrolidine after activation. Commercial assay is 99% with controlled

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
