98% ISO 공장의 대량 크레졸 레드
크레졸 레드 is a greenish powder, ranging from green to dark green or brown-red, slightly soluble in water and very soluble in ethanol but insoluble in acetone or benzene.
Its color changes from orange to yellow between pH 0.2 and 1.8 and from yellow to purple between pH 7.0 and 8.8.
~ 안에 실험실과 환경 보호 산업에서는 산염기 지시약, 염료, 2색 지시약으로 사용됩니다.
Generally, people dilute it to a 0.1% elution or to a 0.04% sodium salt aqueous solution as an indicator.
For example, it is used as a pH-sensitive indicator dye in nano-optical urea biosensor membranes and in heteronuclear-structured fiber-optic pH sensors.
