Glyoxal 40% solution (CAS 107-22-2) is a widely used industrial chemical that presents a unique set of properties and requires careful handling. Understanding these aspects is crucial for safe and effective utilization across various sectors, from textiles to pharmaceuticals. NINGBO INNO PHARMCHEM CO.,LTD. provides this vital intermediate with detailed product information.

Physical Properties:
The most common form of commercial glyoxal is a 40% aqueous solution. This solution typically appears as a colorless to light yellowish transparent liquid. Its density is around 1.265 g/cm³, and it possesses a relatively low melting point of approximately 15°C and a boiling point of about 51°C. These properties indicate that it is a stable liquid under normal storage conditions. Glyoxal is highly soluble in water and readily dissolves in many common organic solvents, which facilitates its incorporation into various formulations and reaction mixtures.

Chemical Characteristics:
As a dialdehyde, glyoxal (C2H2O2) features two highly reactive aldehyde functional groups. This reactivity is the basis for its utility as a crosslinking agent, reacting with amines, hydroxyls, and other functional groups in polymers like proteins, starches, and cellulose. This crosslinking ability is what gives it its effectiveness in applications such as textile finishing and paper strengthening. It can also act as a chemical intermediate in the synthesis of more complex molecules, including those used in pharmaceuticals.

Safety and Handling:
While valuable, Glyoxal 40% solution is a chemical that requires adherence to safety protocols. It is classified as harmful by inhalation and can be irritating to the skin and eyes. There is also a potential for skin sensitization. Therefore, proper personal protective equipment (PPE) is essential when handling glyoxal. This includes wearing chemical-resistant gloves, eye protection (such as safety goggles or a face shield), and appropriate respiratory protection if adequate ventilation is not available or if misting is likely. Adequate ventilation in the work area is paramount to minimize inhalation exposure.

Storage recommendations typically involve keeping containers tightly closed in a cool, dry, and well-ventilated area, away from incompatible materials such as strong oxidizing agents and strong bases. Promptly clean up any spills using appropriate absorbent materials and following safety guidelines.
