Coniferyl alcohol

CAS: 458-35-5

Overview

Coniferyl alcohol (CAS 458-35-5 ), also known as coniferol, is a phenylpropanoid monomer that occurs naturally in plant cell walls as a primary lignin precursor. In industry, it functions as a polymerization building block and biochemical reference standard.

This compound is utilized across research-intensive and process-oriented applications. In pulp and paper research, it is used to study lignin biosynthesis and depolymerization pathways, directly informing the development of more efficient delignification processes.

Biotechnology and life sciences laboratories source it as a high-purity reference compound for enzyme activity assays. These assays particularly involve peroxidases and laccases involved in lignocellulosic biomass conversion for industrial use.

Pharmaceutical and nutraceutical researchers use it as a synthetic intermediate in the preparation of bioactive phenylpropanoid derivatives. It also serves as a model substrate in studies targeting lignin valorization for bio-based material development.

The product is supplied as a solid crystalline powder to ensure stability during transport. It is available primarily in research and fine chemical grades, with purity specifications typically ranging from 98% upward to meet requirements.

These specifications are designed to meet rigorous analytical and synthetic requirements for high-end manufacturing. Packaging is offered in small quantities suited to laboratory procurement, with bulk options available through specialty fine chemical suppliers.
