Chemistry:Vitamin C2

Vitamin C2 or Vitamin C₂ is not a widely recognized term in modern scientific classification. However, it has been historically or erroneously used to refer to various substances, including:

• A proprietary trademarked name for a combination of calcium ascorbate and ascorbyl palmitate, marketed as a blend of "water-soluble" and "fat-soluble" vitamin C.
• Vitamin P, a historical term once used for certain flavonoids, though they are not classified as true vitamins.
• Aesculin (also known as Esculin), a compound sometimes referred to as "Vitamin C2" in older databases, though this designation is not widely accepted.
