CAS 34487-61-1
:Vermelho de fenol sódico
Descrição:
Vermelho de fenol sódico, com o número CAS 34487-61-1, é um indicador de pH comumente utilizado em várias aplicações biológicas e químicas. Aparece como um pó ou sólido cristalino de cor marrom avermelhada e é solúvel em água, exibindo uma mudança de cor de amarelo para vermelho à medida que o pH transita de condições ácidas para ligeiramente alcalinas, tipicamente em torno de pH 6,8 a 8,4. Essa propriedade o torna valioso em meios de cultura celular e experimentos de laboratório para monitorar mudanças de pH. Vermelho de fenol sódico é não tóxico e frequentemente utilizado em diagnósticos médicos e como um corante biológico. Além disso, tem aplicações na indústria alimentícia como um aditivo colorante. Sua estrutura química consiste em um grupo fenólico, que contribui para suas propriedades ácidas, e é classificado como um ácido fraco. Deve-se ter cuidado ao manusear este composto, como com qualquer químico, para garantir a segurança e a eliminação adequada.

CAS:<p>Phenol red is a pH indicator that finds broad applications from chemistry to microbiology. Colour varies from yellow at pH<6.8 (lmax 443nm) through to light red/pink at 6.8<pH<8.2 (lmax 570 nm) to vivid purple/red at pH>8.2. It is widely used in cell culture to monitor pH and for colorimetric titration. For example, phenol red can be used to quantify Br- content in sea or fresh water. It is added to VTM as pH indicator, at the concentration of 10mg/ml, maintaining a pink colour at neutral pH.</p>Fórmula:C19H13NaO5SCor e Forma:Slightly Brown Red PowderPeso molecular:376.36 g/molPhenol Red Sodium Salt ACS (water soluble), 95%

Phenol Red sodium salt is a water soluble pH indicator used in the 6.8 (yellow) to 8.2 (red) range. It is commonly employed in cell biology laboratories as a cell tissue culture pH marker. Under normal conditions, phenol red added to the growth medium will have a pink-red color. Usually 15 mg/l is used to produce this effect. If problems arise, such as dying cells or overgrowth of contaminants, this will cause a change in pH resulting in a change in indicator color. This color change is an indication that the medium needs to be replaced. Additionally, Phenol Red could potentially be useful as a differentiation factor.
