The left side 酉 (yǒu) is a wine jar, a sign used for fermented and chemical substances. The right side 荃 (quán) gives the sound, so think of a jar of chemicals that reads quán: an aldehyde.
醛 is a technical chemistry word that appears mostly in compound names of chemicals. The most common one is 甲醛 (jiǎquán, formaldehyde), often mentioned in news about new furniture or home renovation. Example: 新家具可能有甲醛。(Xīn jiājù kěnéng yǒu jiǎquán.) New furniture may contain formaldehyde.
Common mistake: Learners often confuse 醛 (quán, aldehyde) with 醇 (chún, alcohol) and 酮 (tóng, ketone), since all three share the 酉 radical and name related compounds. Also keep the second tone. It shares its sound with its phonetic part 荃 (quán).
