Rhoduline Violet

Description

Functionally, this compound is used as a dye/biochemical reagent — for example as a staining agent or pH indicator in laboratories, as indicated by industrial suppliers listing it among “biological stains, pH indicators, laboratory reagents.” It’s also used under the name Diethyl Safranine / Methyl Diethyl Safranine for applications requiring a phenazinium‑type dye. Because dyes like this often interact with biological/or chemical substrates, handling typically requires caution, though explicit hazard classification details are less consistently reported in public sources for this specific compound.

Biological stains & laboratory reagents / pH indicators — Many suppliers list Rhoduline Violet under “Biological Stains, pH Indicators and Laboratory Reagents.Write your text here...

Textile and paper dyeing / colourant for fabrics & paper — According to a chemical‑database listing, Rhoduline Violet is commonly used as a dye for fabrics and paper providing a “gorgeous purplish‑red” hue

Electroplating / metal‑surface coloration — Some suppliers categorize Rhoduline Violet among “electroplating liquid dyes,” suggesting use for coloring metals or metal‑coated surfaces during plating.

As a biological stain / lab reagent / indicator dye — the dye’s colour and solubility make it useful to stain tissues, cells, or other biological specimens (or possibly as a pH or general-purpose indicator / reagent dye) in microscopy or histology, though I did not find peer‑reviewed publications describing standard protocols using Rhoduline Violet specifically.

As a fabric or paper dye / pigment — it can impart vivid purplish‑red or red‑violet hues to fibers/paper; useful potentially in textiles, paper‑based products, decorative printing, or crafts.

As a metal-colourant in electroplating or surface finishing — certain dye suppliers market it among electroplating dyes, implying it might be used to colour plated metal surfaces or provide a tinted appearance after platin

There is no robust public scientific literature describing detailed staining protocols, toxicology, stability, or long‑term performance (light‑fastness, wash‑fastness) of Rhoduline Violet. The “biological stain / lab reagent” usage in catalogs seems commercial rather than academically validated.

As far as I found — no comprehensive hazard classification, or regulatory toxicology data for Rhoduline Violet are publicly available. This means that any application — especially industrial, textile, or electroplating — carries unquantified health and environmental risk.

Because many dye catalogues are conservative with wording — they say “for industrial / lab use only” and “not for human or food use” — the use of Rhoduline Violet in any consumer‑facing or food‑related product is likely not approved / not safe.

Lack of published data also means colourfastness under real‑world conditions (washing, light exposure, pH exposure, bleaching, long‑term stability) is unknown. For textile or paper dyeing, this is a major drawback if durability is needed.
