6269-25-6 - Introduction
Pyran-4-(Hydroxymethyl)-5-methoxy (2-(Hydroxymethyl)-phenylene) is an organic compound with the following properties and uses:
Nature:
-Appearance: Pyran-4-one, 2-(hydroxymethyl)-5-methoxy is a white to light yellow solid.
-Solubility: It has low solubility in water, but better solubility in organic solvents.
-Stability: The compound is relatively stable at room temperature, but may be sensitive to light and heat.
Use:
The compound has a variety of applications, including:
-Preservatives and antioxidants in cosmetics and personal care products.
-It can also be used as an intermediate in the pharmaceutical field for the synthesis of other organic compounds.
Method:
Pyran-4-one, 2-(hydroxymethyl)-5-methoxy can be synthesized by the following steps:
1. First, the hydroxymethyl benzyl alcohol (4-methoxy benzyl alcohol) protection. The protection reaction is usually carried out in the presence of a reagent such as hydrofluoric acid or trifluoromethanesulfonic acid.
2. Then, the protected compound is reacted with acetic anhydride (acetic anhydride) and triphenyl phosphate (triphenyl phosphate oxide) to generate an intermediate.
3. Finally, by applying a basic catalyst (such as potassium carbonate) in ethanol, the protecting group is removed to generate pyran-4-one, 2-(hydroxymethyl)-5-methoxy.
Safety Information:
When using pyran-4-one, 2-(hydroxymethyl)-5-methoxy, the corresponding safety procedures should be followed. This compound may be irritating to eyes and skin, please avoid direct contact. Appropriate personal protective equipment, such as lab gloves and goggles, should be used during operation. If taken by mistake or inhaled, seek medical attention immediately.
