Pyranine Introduction

It is a water-soluble yellow-green fluorescent dye, which is often called Solvent Green 7. Its biggest feature is "bright when it meets water", which is not only bright in color, but also sensitive to the change of pH value, and is often used as a pH indicator. In addition to "coloring" soap, hand sanitizer and antifreeze, it can also be made into highlighter and ink. In scientific research and industry, it is also a good helper to detect ions and track water flow, and it is widely used.

Application Areas:

  1. Daily chemical and personal care: Pyranine is widely used for color matching of liquid detergent, soap, shower gel and hand sanitizer, giving products a bright yellow-green appearance.
  2. Functional fluid and industry: it is used for coloring antifreeze, automobile coolant and functional chemicals, and has both dyeing and indicating functions.
  3. Stationery and printing: It is a commonly used fluorescent dye for highlighter, marker ink and special printing ink, with eye-catching colors.
  4. Scientific research and biochemistry: used as pH fluorescence probe in biochemistry and environmental monitoring, or used for ion detection and water flow tracing.
  5. Other technical fields: it can also be used for fluorescent labeling of laser dyes, optical sensors and some polymer materials.

Main Benefits:

  1. Good solubility, convenient application: it is excellent in water solubility, easy to dissolve in water and organic solvents, convenient to prepare and suitable for water-based systems.
  2. Bright fluorescence, eye-catching: it has strong yellow-green fluorescence and bright color, which is very suitable for highlighter and highlight logo.
  3. Dual functions: it can not only color, but also respond sensitively to pH changes, and can be used as a probe for scientific research and industrial detection.

FAQ

Q1:Is the product water-soluble or oil-soluble? Which systems are mainly applicable to? ​

A1: It is a highly water-soluble fluorescent dye, easily soluble in water and other polar solvents. It is mainly suitable for coloring water-based systems (such as antifreeze, cutting fluid and water-based ink) and some daily chemical products (such as hand sanitizer and soap).

Q2:Is its fluorescence performance stable? Will it fade in different pH environments?

A2: It has the strongest fluorescence under alkaline conditions. It is pH sensitive, and its fluorescence will weaken or change color in strong acid environment, which is determined by its chemical characteristics. Its photo-thermal stability is excellent in the pH range of routine daily chemical and industrial application.

Q3:What is the minimum order quantity (MOQ)? What are the packing specifications?

A3: The standard MOQ is 1kg (samples with different specifications can be ordered according to customers' requirements). Conventional packaging is lined with plastic bags and aluminum foil tape, which is sealed and moisture-proof to ensure the safety of long-distance transportation.
