4-Methoxycinnamic Acid CAS 830-09-1

1. Acts 4-Methoxycinnamic acid CAS 830-09-1 as a key intermediate for synthesizing anti-adrenergic drugs like esmolol and anti-diabetic pharmaceutical candidates, leveraging its methoxyphenylpropanoid structure for targeted molecular modification.

2. Serves 4-Methoxycinnamic acid as a core UVB absorber intermediate in cosmetics to formulate sunscreens and daily care products, protecting skin from UV-induced damage and premature aging.

3. Functions as a building block in organic synthesis for preparing flavor esters, specialty polymers and light stabilizers via esterification or condensation reactions.

Store 4-methoxycinnamic acid (CAS 830-09-1, trans-dominant) in sealed amber glass containers at 15–25°C in a cool, dry, dark and well-ventilated area (melting point 170–175°C, non-flammable crystalline powder). Isolate from strong oxidants, bases and reducing agents to avoid degradation and maintain stability. Wear nitrile gloves, safety goggles and lab coats during handling; avoid inhalation, skin/eye contact and ingestion to prevent skin irritation and severe eye irritation (GHS H315, H319, H335). Reseal tightly after use; dispose of waste per local hazardous chemical regulations.

4-Methoxycinnamic acid CAS 830-09-1 is an industrial and research intermediate, not for direct human ingestion in pure form; unregulated intake may cause digestive discomfort and mucosal irritation.

In regulated applications, 4-Methoxycinnamic acid enables synthesis of cardiovascular and anti-diabetic drugs, powers cosmetic UV protection, and supports organic synthesis of high-value specialty chemicals, contributing to medical treatment and product innovation.
