About Oxalyl chloride, 98%

Vaqora Chemicals supplies Oxalyl chloride (Synthesis grade), an acylating agent registered under CAS number 79-37-8 at a purity of 98%. The compound has the formula C2Cl2O2, corresponding to a molecular weight of 126.92 g/mol. Its systematic (IUPAC) name is oxalyl dichloride. Alternative names: Ethanedioyl dichloride and Oxalic dichloride.

In its supplied form it is a colourless to faint yellow liquid. Key physical data: a boiling point of 62-65 °C and a density of 1.5 g/mL at 20 °C. Store in a cool, well-ventilated place, away from sources of ignition, with the container tightly sealed. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

It is commonly used for organic synthesis, catalysis and oxidation reactions. Buyers come mainly from pharmaceutical manufacturing and academic and industrial research.

Standard pack sizes are 100 g and 500 g, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
