Phenol Red Sodium Salt CAS 34487-61-1

1. Phenol Red sodium salt CAS 34487-61-1 is a pH indicator dye widely used in cell culture to monitor pH changes, providing a visual transition from yellow (pH 6.8) to red (pH 8.2) as the medium becomes more basic .
2. Phenol red sodium salt is employed in diagnostic assays, including renal function tests and various colorimetric assays, as well as in histology and hematology applications .
3. Phenol Red sodium salt is utilized in biochemical research to track real-time processes, study enzyme activity, and assess cell viability and growth in tissue culture .
4. Researchers use Phenol red sodium salt in pharmaceutical development and as a tracer in microinjection procedures to visualize injection success.

1. Phenol Red sodium salt CAS 34487-61-1 must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment; it can be stored at room temperature (15-30°C) under desiccating conditions .
2. Phenol red sodium salt is stable indefinitely when stored properly, with some sources recommending storage in a cool, dark place (<15°C) for optimal preservation .
3. The compound is classified with signal word "Warning" and hazard statements H315 (Causes skin irritation), H319 (Causes serious eye irritation), and H335 (May cause respiratory irritation) .
4. Personnel must wear chemical-resistant gloves, safety goggles with side-shields, and protective clothing when handling this substance; a dust mask (type N95) is recommended to avoid inhalation.

1. Isolate the spill area, ensure adequate ventilation, and wear full personal protective equipment including chemical-resistant gloves, safety goggles, and a dust respirator (type N95 or equivalent) .
2. Sweep up Phenol red sodium salt without creating dust using non-sparking tools, or use a vacuum with a HEPA filter, and place the material into a sealed bag or suitable closed container for disposal .
3. Avoid creating dust clouds during cleanup to prevent respiratory exposure; ventilate the area and wash the spill site thoroughly after material pickup is complete .
4. Dispose of collected Phenol red sodium salt material as hazardous waste according to local, state, and federal environmental regulations; Flinn Suggested Disposal Method #26a is one recommended option .

1. Phenol Red sodium salt CAS 34487-61-1 is a nonflammable solid, but fine dust dispersed in air in sufficient concentrations may present a dust explosion hazard in the presence of an ignition source .
2. Use a tri-class dry chemical powder, carbon dioxide, or foam extinguisher to extinguish fires involving the product .
3. Firefighters Phenol red sodium salt should wear self-contained breathing apparatus in pressure-demand, MSHA/NIOSH approved, and full protective gear when handling burning Phenol Red sodium salt .
4. When heated to decomposition, hazardous decomposition products may include toxic fumes of carbon monoxide, carbon dioxide, and sulfur oxides .
