Introduction of 20666-12-0 :

Luminol sodium salt is a chemical that exhibits chemiluminescence with pKa values of 6.74 and 15.1. Luminol sodium salt exhibits chemiluminescence (CL) at 425 nm λmax. Luminol sodium salt is commonly used in forensics as a diagnostic tool for the detection of blood stains[1]. In Vitro: Luminol concentration is an important factor that affects Chemiluminescence (CL) intensity. The intensity of Luminol chemiluminescence (LCL) does not depend on the concentration of Luminol alone, but also on other factors like concentration of oxidizing agents, enzymes, and pH. Maximum recorded CL intensity was at a Luminol concentration of 0.3 mM. CL intensity increased linearly with increasing concentrations of Luminol in the range of 0.01 to 0.3 mM. However, further increases of Luminol concentration caused a decrease in CL intensity[1].
