O-Cresolphthalein (CAS 596-27-0) is a synthetic organic compound belonging to the phthalein family. It functions effectively as an acid-base indicator, transitioning from colorless in acidic environments to a distinct violet-red color in alkaline conditions, typically within the pH range of 8.2 to 9.8.
In the Indian market, this chemical is a staple for diagnostic laboratories and manufacturers of clinical chemistry reagents. It is specifically valued for its role in the complexometric titration of calcium ions, a fundamental process in medical diagnostic testing kits produced across major industrial hubs like Mumbai, Ahmedabad, and Hyderabad.
When procuring O-Cresolphthalein, buyers should prioritize suppliers providing a Certificate of Analysis (CoA) confirming high assay purity and low residue levels. Given its sensitivity, sourcing from reputable distributors who ensure moisture-proof packaging is essential to maintain the structural integrity and shelf life of the reagent.
O-Cresolphthalein pricing in India depends on grade, order quantity, and delivery location, and it moves with market conditions — so a single fixed price is rarely accurate for a specific requirement.
