o-Cresolphthalein
Certificado ISO 9001:2015 e ISO 14001:2015 · Suministro a laboratorios e industria desde el año 2000 · Certificado de Análisis (CoA) con cada lote
o-Cresolphthalein is a synthetic organic compound primarily used as a pH indicator in analytical chemistry, particularly for detecting alkaline solutions (pH 8.2–9.8). It appears colorless in acidic and neutral conditions but turns bright pink in strongly basic environments, making it ideal for titrations and laboratory testing. This chemical has a CAS number of 596-27-0, with the molecular formula C22H18O4 and a molecular weight of 346.38. It is stable at ambient storage conditions and carries no signal word for hazard classification. Molekula supplies o-Cresolphthalein from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
