## Description

This Phenolphthalein Indicator solution is manufactured in our USA laboratory by experienced chemists using strict quality control procedures. It is commonly used with acid and base titrations as well a "neutralization" indicator for determining when excess base such as sodium hydroxide or potassium hydroxide is present. Our formulation does NOT contain alcohol but uses safer propylene glycol thus avoiding the flammability hazard. **Please inquire for a Certificate of Analysis/Conformance**

### ⭐⭐⭐⭐⭐ Exactly what I needed
*by A***R on November 16, 2024*

Yes, phenolphthalein is an odd choice, but I needed some for a science experiment. This arrived promptly and worked as expected. Happy with my purchase!

### ⭐⭐⭐⭐⭐ Works good, delivery good
*by M***E on June 21, 2023*

I recieved the chemical on time as expected. And more importantly it works perfectly. Maybe I shouldn't be too pessimistic, however the first bottle I purchased 2 years ago didn't work as expected. This bottles color is bright magenta when reacting. The bottles seam to seal well. My old bottle worked well for about a year, then evaporated to almost nothing in 2 months. Time will tell. I will update this in a year.
