Product Overview
As a China-based manufacturer, Alfa Chemical supplies high-purity 5-Formyl-2-methoxybenzonitrile (CAS 21962-50-5), a dual-functional aromatic building block containing both an aldehyde and a nitrile group. Also known as 2-Methoxy-5-formylbenzonitrile or 3-Cyano-4-methoxybenzaldehyde, this compound is widely used as an intermediate in pharmaceutical and agrochemical synthesis, as well as a versatile building block for organic chemistry research.
The compound is supplied as a white to off-white solid with a purity of ≥ 98% (HPLC). Its two reactive functional groups enable diverse synthetic transformations: the aldehyde group can undergo condensation, reductive amination, and Wittig reactions, while the nitrile group can be converted to amines, amides, and carboxylic acids. This dual reactivity makes it a valuable scaffold for the synthesis of indole derivatives, heterocyclic compounds, and other biologically active molecules.
We offer flexible packaging from 100mg R&D samples to 10g and custom quantities with fast worldwide delivery. For similar organic building blocks and pharmaceutical intermediates, explore our related product range.
