Product Description

Property

CAS No.: 60-11-7 Formula: C14H15N3 Molecular Weight: 225.28900

Description

Methyl yellow, or C.I. 11020, is a chemical compound which may be used as a pH indicator.
Methyl yellow (pH indicator) below pH 2.9 above pH 4.0 2.9 ⇌ 4.0; In aqueous solution at low pH, methyl yellow appears red. Between pH 2.9 and 4.0, methyl yellow undergoes a transition, to become yellow above pH 4.0.
