97% Purity MMDPPA CAS 858215-05-1

Procaine Hydrochloride CAS 51-05-8 is the water-soluble hydrochloride salt of procaine. It is the specific formulation used in clinical medicine, famously marketed under the brand name ​Novocain. While its use in mainstream practice has diminished, it remains a historically pivotal drug and is still employed in specific medical and therapeutic contexts.  

3′-Methoxyphenacyl Bromide CAS 5000-65-7 is a specialized, light-sensitive α-bromo ketone​ primarily valued as a photoremovable protecting group reagent​ for carboxylic acids and as an alkylating agent. Its meta-methoxy substitution can slightly alter its photolytic and electronic properties compared to the parent phenacyl bromide. Handling requires strict precautions due to its lachrymatory nature and sensitivity to light and moisture. For researchers in chemical biology, organic synthesis, and photochemistry, it provides a classic and effective tool for light-controlled deprotection and molecular conjugation.  

4-(tert-Butyl)-2,6-diformylphenol CAS 84501-28-0 is a premium bifunctional building block in organic and coordination chemistry. Its value lies not just in its reactivity, but in its specifically engineered structure that delivers superior performance in advanced applications.  

4-Bromo-3-hydroxybenzoic acid CAS 14348-38-0 is a premium, multifunctional aromatic building block engineered for complexity-driven synthesis. Its core value lies in the strategic placement of three distinct, orthogonally reactive functional groups on a benzene ring, making it an indispensable tool for convergent molecular construction in advanced research and development.  

Ethyl β-Oxo-1,3-benzodioxole-5-butanoate CAS 31127-23-8 is a β-ketoester derivative​ featuring a 1,3-benzodioxole (methylenedioxyphenyl) aromatic system. Structurally, it consists of a benzodioxole ring attached through a three-carbon chain to an ethyl β-ketoester functional group (-CO-CH₂-COOEt). This makes it a versatile bifunctional building block​ for organic synthesis, combining the electronic properties of the benzodioxole group with the high reactivity of a β-ketoester.

4-Nitrophenyl 3-(Benzo[d][1,3]dioxol-5-yl)-2-methylpropanoate is a chirally defined, pre-activated acylating agent​ that combines a metabolically stable benzo[1,3]dioxole (piperonyl) pharmacophore with the exceptional reactivity of a 4-nitrophenyl ester. It enables the efficient, racemization-free introduction of a complex, chiral acid moiety under mild conditions, making it invaluable for advanced synthetic and bioconjugation chemistry. 4-Nitrophenyl 3-(Benzo[d][1,3]dioxol-5-yl)-2-methylpropanoate is a specialty ester​ designed as a reactive biochemical or synthetic intermediate. Its structure strategically combines three key units: (1)A 3-(benzo[1,3]dioxol-5-yl)-2-methylpropanoic acid​ (piperonyl-substituted, chiral acid) moiety. (2)A 4-nitrophenyl​ ester leaving group. This design makes it an activated ester, where the 4-nitrophenol is an excellent leaving group, facilitating efficient acyl transfer reactions under mild conditions.  

2'-Ethoxyacetophenone CAS 2142-67-8 is a specialized aromatic ketone characterized by an ethoxy substituent at the orthoposition relative to the acetyl group. This structural feature imparts distinct chemical and physical properties, making it a privileged building block for synthesizing complex molecules, particularly in the flavor/fragrance and pharmaceutical sectors.  

2-Amino-5-bromobenzoic acid CAS 5794-88-7 is a highly versatile aromatic building block that integrates three distinct functional groups—an amine, a carboxylic acid, and an aryl bromide—into a single, synthetically valuable scaffold. This multifunctionality makes it a crucial intermediate in pharmaceutical and advanced materials chemistry.
