Dodecanol_Lauryl Alcohol C12 Alcohol L-23 (CAS No.: 68439-50-9) has the full chemical name C12-14 fatty alcohol. It is a mixture mainly composed of 1-dodecanol (lauryl alcohol, molecular formula C₁₂H₂₆O) and a small amount of C14 fatty alcohol (molecular formula C₁₄H₃₀O). According to the National Chemical Industry database, the molecular weight of this product ranges from approximately 186 to 214 (average about 194), with an active content of no less than 99%, making it a high-purity fine chemical raw material.
At room temperature, the product appears as a colorless liquid or white waxy solid (melting point 23~25°C). It exhibits typical primary alcohol chemical properties, belongs to nonionic surfactants, with an HLB value of about 1.3. Its core functional group is a terminal hydroxyl group (-OH), which provides good chemical reactivity and allows for various derivatization reactions such as ethoxylation, sulfation, and esterification.
