Diazonaphthoquinone 2-2-4-4 THBP Building Block

DNQ-THBP 2-2-4-4 Building Block
Diazonaphthoquinone · tetrahydroxy benzophenone (THBP) ester

DNQ-THBP is the industry-standard photoactive compound (PAC) for positive-tone g-line (436 nm) and i-line (365 nm) microlithography. Novolak resin acts as the base matrix; THBP esterified with DNQ functions as the PAC. Orion supplies this building block alongside Orion P-1403, P-1610 and P-3101 grades.
