English name: Methyl red; "MR; C.I. 13020; Acid Red 2; 2-[4-(Dimethylamino)phenylazo]benzoic acid
Other names: Jia Hong; Alkane red Methane red P-dimethylamino-azobenzo-carboxylic acid Acid Red 2 2-[[4-(dimethylamino) phenyl] azo] benzoic acid
CAS Number: 493-52-7
C15H15N3O2 = 269.30
Level: AR
pH color range: 4.5(red) to 6.2(yellow)
Loss on drying: ≤1.0%
Ethanol dissolution test: Qualified
Mass absorption coefficient (λ1, pH 4.5) /[L/ (cm•g)] : ≥130.0
Mass absorption coefficient (λ2, pH 6.2) /[L/ (cm•g)] : ≥70.0
Incineration residue: ≤0.2%
Maximum absorption wavelength (λ1, pH 4.5)/(nm) : 523-528
Maximum absorption wavelength (λ2, pH 6.2)/(nm) : 427-437
Properties: Lustrous purple crystals or red-brown powder. It is soluble in ethanol and acetic acid and almost insoluble in water. After being stored for a long time, the sensitivity of ethanol solution can be significantly reduced due to the esterification of carboxyl groups
Usage: Biochemical research. Live staining of protozoa Acid-base indicator. Titrate ammonia, weak organic bases and alkaloids, but not organic acids except oxalic acid and picric acid. It can be combined with bromocresol green and methylene blue to form a mixed indicator to shorten the color change range and enhance the sensitivity of color change. Adsorption indicators for precipitation titration, such as titrating fluoride ions with thorium nitrate. Verify free chlorine and chlorite
Save: RT, away from light
