Squaric Acid, scientifically known as 3,4-Dihydroxy-3-cyclobutene-1,2-dione and identified by CAS number 2892-51-5, is a fascinating organic compound with a unique structure and a wide range of applications. Its chemical properties make it a valuable asset in fields ranging from pharmaceuticals to materials science. NINGBO INNO PHARMCHEM CO.,LTD. is a leading supplier of this essential chemical, offering it with high purity to meet the demands of diverse industries.

Chemically, Squaric Acid is a diprotic organic acid, meaning it can donate two protons. Its structure features a four-membered ring with two ketone groups and two hydroxyl groups, leading to significant resonance stabilization of its conjugate base, the squarate dianion. This resonance contributes to its high acidity, with pKa values that make it a stronger acid than typical carboxylic acids. This acidic nature is key to many of its synthetic uses.

The physical appearance of Squaric Acid is typically a beige crystalline powder. It exhibits good solubility in water but has limited solubility in many nonpolar organic solvents. These properties influence how it is handled and utilized in various chemical processes. When considering purchasing Squaric Acid, understanding these characteristics is vital for effective application.

The applications of Squaric Acid are notably diverse. It serves as a crucial intermediate in the synthesis of squaraine dyes, which are employed in advanced materials for their unique optical and electronic properties. In the pharmaceutical sector, Squaric Acid is used in the synthesis of various active pharmaceutical ingredients (APIs), including some antibiotics and anti-inflammatory agents. Its derivatives have also been explored for therapeutic uses, such as in the treatment of warts and alopecia. For companies looking to buy Squaric Acid, its versatility makes it a strategic choice.
