Methyl 4-Aminobenzoate — CAS 619-45-4
Methyl 4-Aminobenzoate — CAS 619-45-4
Methyl 4-aminobenzoate (CAS 619-45-4), also known as methyl para-aminobenzoate or PABA methyl ester, is an aromatic amine compound used primarily as a pharmaceutical intermediate, chemical synthesis building block, and UV-absorbing agent. UAB An Group Export supplies it in technical and pharmaceutical grades, matched to each customer's synthesis and application requirements.
It is used across pharmaceutical intermediate synthesis, organic dye and pigment manufacturing, UV absorber applications, and select specialty chemical formulations. Its para-aminobenzoate structure makes it a versatile reactive intermediate for acylation, coupling, and condensation reactions in pharmaceutical and fine chemical synthesis.
For industrial buyers, supply is coordinated around grade, purity, volume, packaging, and delivery destination, in line with applicable product and pharmaceutical handling regulations. Bulk and commercial orders are both handled — send your requirements and we'll prepare a quote covering supply, packaging, logistics, and delivery.
Regulatory Notice
Methyl 4-aminobenzoate contains a primary aromatic amine functional group. Cosmetic formulators and buyers should be aware that primary aromatic amines as a structural class are subject to significant regulatory scrutiny in cosmetic applications across EU and major markets. PABA-derived UV filter ingredients have been largely phased out of modern sunscreen formulations in the EU and are subject to specific regulatory review under EU Cosmetics Regulation. Buyers intending cosmetic or sunscreen applications are responsible for verifying the regulatory status of this ingredient in their specific market and application before formulating. Pharmaceutical-grade applications are subject to applicable pharmacopeia and regulatory requirements in the buyer's jurisdiction.
Key Applications
Pharmaceutical IntermediateA widely used building block in pharmaceutical synthesis — used in the production of local anesthetic compounds, antimicrobial agents, and other pharmaceutical active ingredients requiring a para-aminobenzoate scaffold.
Organic Dye & Pigment ManufacturingUsed as a coupling component and intermediate in the synthesis of azo dyes, disperse dyes, and related colorant structures for textile and industrial applications.
UV Absorber ApplicationsHas UV-absorbing properties in the UVB range — used in select industrial and specialty UV-protection formulations. Note: its use as a cosmetic UV filter is subject to regulatory review and has been largely superseded by newer UV filter molecules in major regulated markets.
Chemical SynthesisUsed as a reactive intermediate in organic synthesis for acylation, diazotization, coupling, and other chemical transformations requiring a para-aminobenzoate starting material.
