For professionals in the chemical and manufacturing sectors, a deep understanding of a dye's chemical properties is fundamental to its successful application. Solvent Red 49, identified by CAS No. 509-34-2, is a prime example of a dye whose utility is directly linked to its specific molecular characteristics. As a prominent manufacturer and supplier of this vital industrial dye, we believe it’s important to illuminate these scientific underpinnings.

Chemical Identity of Solvent Red 49

Solvent Red 49 is recognized within the chemical community by several identifiers, underscoring its established presence and distinct nature:

  • CAS Number: 509-34-2 – This unique numerical identifier is crucial for unambiguous identification in chemical databases and regulatory contexts.
  • Molecular Formula (MF): C₂₈H₃₀N₂O₃. This formula indicates the precise atomic composition of the molecule, comprising carbon, hydrogen, nitrogen, and oxygen atoms in specific ratios.
  • Molecular Weight (MW): Approximately 442.55 g/mol. This value is essential for stoichiometric calculations in formulation and synthesis.
  • EINECS Number: 208-096-8. The European Inventory of Existing Commercial Chemical Substances (EINECS) number confirms its presence in the European market and its regulatory standing.
  • Synonyms: Often referred to as Oil Pink B or Rhodamine B Base, these common names reflect its appearance and historical classification.

These details are critical for R&D scientists and procurement managers seeking specific chemical inputs. When you buy Solvent Red 49, understanding these specifications ensures you are acquiring the correct, high-purity material for your application.

Key Properties Driven by its Chemistry

The molecular structure of Solvent Red 49 dictates its solubility, color, and stability. Its design allows it to readily dissolve in organic solvents and oils, a characteristic that forms the basis of its classification as a 'solvent' dye. This fat-solubility is a direct consequence of the non-polar portions of its molecule, enabling it to interact favorably with oily or hydrocarbon-based mediums, rather than polar ones like water.

The molecule’s chromophore (the part responsible for color) results in its signature vibrant rose red hue. Furthermore, the overall molecular architecture contributes to its noted thermal stability and resistance to light degradation, making it suitable for demanding industrial environments where color must be maintained under challenging conditions. These inherent properties are meticulously controlled during our manufacturing process to ensure consistency and reliability.

Why Sourcing Matters: Purity and Consistency
