Ready-to-use 0.02% hydroalcoholic neutral red solution, ideal as a pH colour indicator around neutrality.
Clear transition range: red below pH 6.8 and yellow above pH 8.0, enabling easy visual endpoint detection in titrations.
Flammable and eye-irritant reagent (H225, H319); must be handled in a fume hood with goggles, gloves and lab coat under CLP-compliant procedures, for laboratory use only.
AllChimie neutral red 0.02% hydroalcoholic solution is a pH indicator designed for use around the neutral range. It appears red in acidic to slightly acidic media (pH < 6.8) and yellow in basic media (pH > 8.0), providing a reliable visual signal at the equivalence point in titrations and pH checks. The dye (C15H17N4Cl, M = 288.78 g/mol, CAS 553-24-2) is dissolved in a hydroalcoholic mixture, giving good miscibility with aqueous systems. Supplied in a 125 mL bottle, it is suitable for QC, R&D and teaching laboratories. As a flammable and eye-irritant solution, it must be handled in a fume hood with appropriate PPE and within CLP risk management procedures. For laboratory use only. Not intended for medical or in vitro diagnostic use unless explicitly stated by the manufacturer. The user is responsible for verifying regulatory compliance in their country (France and EU).
