Clorhidrato de procaína CAS 51-05-8 Es la sal hidrocloruro de procaína soluble en agua. Es la formulación específica utilizada en medicina clínica, conocida por su nombre comercial:NovocaínaSi bien su uso en la práctica general ha disminuido, sigue siendo un fármaco históricamente fundamental y aún se emplea en contextos médicos y terapéuticos específicos. 

cis-Isolimonenol CAS 22972-51-6 is a monocyclic monoterpenoid alcohol belonging to the carveol family. It features a cyclohexene ring with a hydroxyl group at position 2, a methyl group at position 1, and an isopropenyl group at position 4. The specified stereochemistry (1S,4R) indicates the absolute configuration of the two chiral centers, making it the (+)-cis isomer of carveol. The "cis" designation refers to the relative orientation of the hydroxyl and isopropenyl groups being on the same side of the cyclohexene ring plane. The molecule contains a conjugated system between the cyclohexene double bond and the hydroxyl group, influencing its chemical reactivity.    

MMDPPA CAS 858215-05-1 is comprised of a ​1,3-benzodioxole (methylenedioxyphenyl) moiety​ connected via a three-carbon chain to a ​primary amide (-CONH₂) group. The presence of a methyl substituent at the alpha-carbon (C-2) of the propanamide chain creates a chiral center, resulting in (R)- and (S)-enantiomers. The benzodioxole ring is a common pharmacophore known to influence metabolic stability and receptor binding.  

L-PAC CAS 1798-60-3(L-Phenylacetylcarbinol), also known as (R)-1-Hydroxy-1-phenylpropan-2-one, is a pivotal ​chiral pharmaceutical intermediate. It is most renowned as the key precursor in the industrial biosynthesis of ​L-ephedrine and pseudoephedrine, widely used decongestants and stimulants.

2-Bromo-3'-chloropropiophenone CAS 34911-51-8 is a halogenated aromatic ketone that serves as a ​specialized synthetic intermediate​ in organic and medicinal chemistry. Its structure, featuring both a reactive α-bromo ketone moiety and a halogenated aromatic ring, makes it a versatile but sensitive building block for constructing more complex molecules, particularly in pharmaceutical research.  

2-Bromo-4-chloropropiophenone CAS 877-37-2 is a halogen-substituted α-bromo ketone that functions as a ​specialized chemical intermediate. It is structurally analogous to its isomer 2-bromo-3'-chloropropiophenone but distinguished by the position of the chlorine atom on the aromatic ring. Due to its high reactivity, it is a valuable building block in organic synthesis, particularly in the formation of C–N bonds and heterocycles, and is subject to stringent regulatory control.

2-Bromo-1-phenylpentan-1-one CAS 49851-31-2 is an ​α-bromo aromatic ketone​ belonging to the class of ​α-halogenated alkyl aryl ketones. It is characterized by an elongated alkyl chain (pentyl) compared to its more common propiophenone analogs. This compound serves exclusively as a ​specialized and highly reactive synthetic intermediate​ in organic chemistry, and its possession and use are subject to stringent international controls due to its role as a precursor to controlled substances.  

4-Methylpropiophenone CAS 5337-93-9 (also commonly referred to as para-methylpropiophenone or 4'-methylpropiophenone) is a simple aromatic ketone that serves as an important ​chemical intermediate​ in organic synthesis. Its structure features an electron-donating methyl group on the aromatic ring, which modifies its reactivity compared to unsubstituted propiophenone. It is a known precursor in both legitimate pharmaceutical synthesis and illicit drug manufacturing, making it a ​controlled substance​ in many jurisdictions.
