UNSPSC 12171502: Phthalein dyes

UNSPSC 12171502 Phthalein dyes is a Commodity code that covers synthetic dyes used in laboratory testing, quality control, water analysis, and industrial coloring applications. State and local governments procure phthalein dyes primarily for environmental compliance testing—particularly pH indicator solutions used in municipal water quality monitoring and wastewater treatment operations—and for use in public health laboratories and educational institutions. The code also encompasses phenolphthalein and related phthalein-based compounds sourced as bulk chemical supplies or pre-packaged reagent kits.

The recent-opportunities block contains no postings under this code, indicating minimal state and local procurement activity at present. The absence of recent solicitations suggests either very low demand, direct purchasing through chemical supply contracts coded elsewhere, or use through cooperative purchasing vehicles that do not post individual phthalein-dye opportunities as separate notices. Firms pursuing this code should monitor for bundled chemical-supply RFQs or standing offers from state procurement offices rather than expect discrete phthalein-dye solicitations.
