CAS 34487-61-1 — فينول ريد، ملح الصوديوم قابل للذوبان في الماء

Phenol Red, sodium salt water soluble is a pH indicator dye used primarily in biological buffers, cell culture media, and biochemical assays to visually monitor pH changes around neutral ranges (6.8–8.4). It transitions from yellow to red as the pH increases, making it ideal for applications requiring precise pH tracking. CAS 34487-61-1, molecular formula C19H13NaO5S (MW 376.36), stored at ambient conditions. Signal word: Warning. Molekula supplies Phenol Red, sodium salt water soluble from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
