I. Product Overview and Basic Information
4-Cyano-2-methoxybenzaldehyde, also known as 4-cyano-2-methoxybenzaldehyde in Chinese, is an important aromatic nitrogen-containing heterocyclic compound with extensive applications in pharmaceuticals, fine chemicals, and dye synthesis. The CAS number of this product is 21962-45-8, with a molecular formula of C₉H₇NO₂, a molecular weight of 161.16, and an EINECS number of 804-777-4.
This product is also known by several commonly used synonyms, including 4-Formyl-3-methoxybenzonitrile and 2-Methoxy-4-cyanobenzaldehyde, which are used in international trade and academic literature. As a benzaldehyde derivative, its molecular structure contains three key functional groups: a cyano group (-CN), a methoxy group (-OCH₃), and an aldehyde group (-CHO), endowing it with unique chemical reactivity and diverse synthetic application potential.
II. Physicochemical Properties
The physicochemical properties of 4-Cyano-2-methoxybenzaldehyde are as follows:
Appearance: White powder
Melting Point (M.P.): 109–111℃
Boiling Point (B.P.): 318℃
Density: 1.18 g/cm³
Flash Point (F.P.): 138℃

III. Application Fields and Market Prospects
1. Key Intermediate for Non-Steroidal Mineralocorticoid Receptor Antagonist (Finerenone)
One of the most important applications of 4-Cyano-2-methoxybenzaldehyde is as an intermediate for Finerenone (non-steroidal mineralocorticoid receptor antagonist). Finerenone is a novel oral medication primarily used for the treatment of diabetic kidney disease and chronic heart failure. It works by selectively antagonizing mineralocorticoid receptors to reduce inflammation and fibrosis, thereby protecting cardiac and renal function. As the global number of diabetes and cardiovascular disease patients continues to grow, the market demand for Finerenone is rapidly increasing, directly driving the demand growth for its key intermediate—4-Cyano-2-methoxybenzaldehyde.
2. Fine Organic Synthesis
In the field of fine organic synthesis, 4-Cyano-2-methoxybenzaldehyde is widely used for constructing complex aromatic compounds due to its multi-functional group structure. Its aldehyde group can undergo condensation reactions with amines and alcohols, and the cyano group can be converted into carboxylic acid, amide, or amine derivatives through hydrolysis, reduction, and other reactions, providing important structural units for the synthesis of drug molecules, functional materials, and pesticide active ingredients.
3. Dye Intermediate
This product can also be used as a dye intermediate. Its aromatic skeleton and modifiable functional groups enable it to participate in the synthesis of precursors for azo dyes, fluorescent dyes, and high-performance pigments, meeting the demand for high-quality dyes in the textile, printing, and coating industries.
4. Market Trends
As the global pharmaceutical industry shifts toward precision medicine and innovative drug development, and with the deepening of green chemistry and sustainable development concepts, the market demand for high-purity, low-impurity pharmaceutical intermediates continues to expand. As a core raw material for blockbuster drugs such as Finerenone, 4-Cyano-2-methoxybenzaldehyde has broad market prospects and is expected to maintain stable growth over the next 5–10 years.
