4-Aminobenzoic acid methyl ester（Cat No.:R058347）, also known as methyl 4-aminobenzoate or benzocaine, is an aromatic ester derived from para-aminobenzoic acid (PABA). It appears as a white, crystalline powder and is commonly used as a local anesthetic due to its ability to block nerve signal transmission. Its structure includes an amino group and a methyl ester, making it reactive in further derivatization for pharmaceutical and chemical synthesis. Benzocaine is widely applied in topical formulations, lozenges, and ointments for pain relief and is also used in organic synthesis as a functionalized aromatic intermediate.
