Description

N-Boc-3,4-dihydro-2(1H)-quinolinone (CAS No. 194979-77-6) is a high-purity, synthetic organic compound with the molecular formula C₁₄H₁₇NO₃. Also known as tert-butyl 2-oxo-3,4-dihydroquinoline-1-carboxylate, this Boc-protected dihydroquinolinone derivative is a versatile intermediate in pharmaceutical and agrochemical research. The compound features a reactive lactam (2-quinolinone) core and a tert-butoxycarbonyl (Boc) protecting group, making it ideal for selective deprotection and further functionalization under mild conditions. Supplied as a white to off-white crystalline powder, it is characterized by excellent stability under standard storage conditions. Suitable for use in peptide coupling, heterocyclic synthesis, and medicinal chemistry applications, this product is rigorously tested for purity (typically ≥95% by HPLC) and is available in research quantities with comprehensive analytical data (NMR, MS, HPLC).
