Salmon-Caprylate (6-Chloro-3-indolyl caprylate) | ASE-909 | C8 Esterase Substrate
Salmon-Caprylate
6-Chloro-3-indolyl caprylate (C8 Esterase)
Precision chromogenic substrate for C8 esterase detection. Essential for differential identification of Salmonella, Pseudomonas, and fungal species in clinical diagnostics and food safety applications.
🏆 Diagnostic Specialist
🔬 C8 Esterase Detection Mechanism
Salmon-Caprylate undergoes esterase-catalyzed hydrolysis at the C8 (caprylate) ester bond, releasing 6-chloro-3-indoxyl which rapidly oxidizes to form a distinctive salmon-red precipitate:
↓ (C8 Esterase/Lipase)
6-Chloro-3-indoxyl + Caprylic acid
↓ (Spontaneous oxidation)
Salmon-Red Indigoid Precipitate
