Description

Chromate(3-), Bis[6-5-Chloro-2-(Hydroxy-κ.O)-4-Nitrophenylazo-κ.N1]-5-(Hydroxy-κ.O)-1-Naphthalenesulfonato(3-)-, Trisodium is a high-purity, organometallic coordination complex primarily used as a specialized colorant and analytical reagent. This compound matters for its unique chromophoric properties derived from its azo and sulfonate groups coordinated with chromium, offering specific color and stability characteristics. It is needed by manufacturers in the dye and pigment industry, as well as research laboratories developing advanced materials and chemical sensors.

Application

• Specialized dye and pigment synthesis for high-performance applications.
• Manufacturing of colorants for inks, coatings, and specialty plastics.
• Analytical chemistry as a chromogenic reagent or complexometric indicator.
• Research and development of novel coordination compounds and metal-organic frameworks (MOFs).
• Potential use in the formulation of light-sensitive or photographic chemicals.
• Laboratory reagent for educational and analytical purposes.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request, detailing parameters such as chromium content, purity by HPLC, and heavy metal limits. We adhere to strict in-process controls to guarantee batch-to-batch consistency for our B2B partners.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This material is light-sensitive (store away from light) and may be hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use.
