(DHQ)2Pyr(CAS: 149820-65-5)

(DHQ)2Pyr is a yellow crystalline solid with a molecular weight of approximately 328.4 g/mol. It is slightly soluble in common organic solvents like ethanol and acetone. Chemically, it is moderately reactive, particularly towards nucleophilic aromatic substitution reactions. Its solubility and reactivity make it useful in organic synthesis and catalysis.

(DHQ)2Pyr can be synthesized by the condensation of 1,1'-biphenyl-2,2'-dicarboxaldehyde with 1,1'-biphenyl-2,2'-diol in the presence of a base. Commonly, sodium hydroxide is used as the base to facilitate the reaction, yielding a product with high selectivity and good yield under mild conditions.

(DHQ)2Pyr is used in various industries, including pharmaceuticals for chiral synthesis, organic synthesis for the production of polymers, and sensor technology for detecting specific chemical species. Its applications also extend to semiconductor manufacturing for its role in photolithography processes.

When handling (DHQ)2Pyr, wear appropriate personal protective equipment (PPE) such as gloves and goggles. Store it in a fume hood to minimize inhalation risks. In case of spill, use appropriate absorbent materials and follow standard laboratory safety procedures. Always consult the Safety Data Sheet (SDS) for specific handling and disposal instructions.
