Salinazid (Cat No.:I035950) is a hydrazone derivative combining isonicotinic acid hydrazide (isoniazid) and salicylaldehyde. It functions as a tuberculostatic agent by disrupting mycobacterial cell wall biosynthesis—particularly inhibiting mycolic acid formation—making it effective against Mycobacterium tuberculosis, including isoniazid-resistant strains. Developed in the mid-20th century, it appears as a white crystalline solid (mp 232–233 °C, micro‑soluble in water but soluble in organic solvents) . It is used as a second‑line anti‑TB therapy and in research settings to study antimicrobial activity and drug‑resistance mechanisms.
