Propantheline

methylbis(propan-2-yl)[2-(9H-xanthene-9-carbonyloxy)ethyl]azanium

C23H30NO3+ (368.22255700000005)

Propantheline is only found in individuals that have used or taken this drug. It is a muscarinic antagonist used as an antispasmodic, in rhinitis, in urinary incontinence, and in the treatment of ulcers. At high doses it has nicotinic effects resulting in neuromuscular blocking. [PubChem]The action of propantheline is achieved via a dual mechanism: (1) a specific anticholinergic effect (antimuscarinic) at the acetylcholine-receptor sites and (2) a direct effect upon smooth muscle (musculotropic).

Erythrosine is a dye used in food and feed additives. Prohibited in U.S.A. and Norway Erythrosine is a cherry-pink synthetic fluorone food coloring. It is the disodium salt of 2,4,5,7-tetraiodofluorescein. Its maximum absorbance is at 530 nm in an aqueous solution, and it is subject to photodegradation.[citation needed]; It is used as a food coloring, in printing inks, as a biological stain, a dental plaque disclosing agent and a radiopaque medium. It is commonly used in sweets and foods marketed to children such as cake icing and cake-decorating gels. It is also used to color pistachio shells. While commonly used in most countries of the world, erythrosine is rarely used in the United States due to its known hazards, with Allura Red AC (Red #40) being generally used instead. However, Allura Red AC is banned in many European countries because it is an azo dye, despite the fact that it has fewer known health risks than Erythrosine D019995 - Laboratory Chemicals > D007202 - Indicators and Reagents > D049408 - Luminescent Agents D004396 - Coloring Agents > D005456 - Fluorescent Dyes > D005452 - Fluoresceins Dye used in food and feed additives.

Rhodamine B

N-[9-(2-Carboxyphenyl)-6-(diethylamino)-3H-xanthen-3-ylidene]-N-ethylethanaminium(1+), 9ci

C28H31N2O3+ (443.23345559999996)

Rhodamine B (RhB), also known as rhodamine 610 chloride (CAS: 81-88-9), belongs to the class of organic compounds known as xanthenes. These are polycyclic aromatic compounds containing a xanthene moiety, which consists of two benzene rings joined to each other by a pyran ring. Rhodamine B is a highly-soluble, basic, red, synthetic dye that is widely used in many industries (e.g. paper, plastic, textiles, ceramics, cosmetics). In the past, it was used extensively as a low-cost food colourant (e.g. in paprika- and chilli-containing foods) but it has since been prohibited for use as a food additive due to its carcinogenicity, reproductive and developmental toxicity, and neurotoxicity (PMID: 30463493). Due to its photostability and solubility, rhodamine B is also used as a fluorescent dye to stain biological tissues (PMID: 28957318). Rhodamine B /ˈroʊdəmiːn/ is a chemical compound and a dye. It is often used as a tracer dye within water to determine the rate and direction of flow and transport. Rhodamine dyes fluoresce and can thus be detected easily and inexpensively with fluorometers. Rhodamine B is used in biology as a staining fluorescent dye, sometimes in combination with auramine O, as the auramine-rhodamine stain to demonstrate acid-fast organisms, notably Mycobacterium. Rhodamine dyes are also used extensively in biotechnology applications such as fluorescence microscopy, flow cytometry, fluorescence correlation spectroscopy and ELISA.[citation needed] Rhodamine B is often mixed with herbicides to show where they have been used.[2] It is also being tested for use as a biomarker in oral rabies vaccines for wildlife, such as raccoons, to identify animals that have eaten a vaccine bait. The rhodamine is incorporated into the animal's whiskers and teeth.[3] Rhodamine B is an important hydrophilic xanthene dye well known for its stability and is widely used in the textile industry, leather, paper printing, paint, coloured glass and plastic industries.[4] Rhodamine B (BV10) is mixed with quinacridone magenta (PR122) to make the bright pink watercolor known as Opera Rose.[5] Rhodamine B can exist in equilibrium between two forms: an "open"/fluorescent form and a "closed"/nonfluorescent spirolactone form. The "open" form dominates in acidic condition while the "closed" form is colorless in basic condition.[6] The fluorescence intensity of rhodamine B will decrease as temperature increases.[7] The solubility of rhodamine B in water varies by manufacturer, and has been reported as 8 g/L and ~15 g/L,[1] while solubility in alcohol (presumably ethanol) has been reported as 15 g/L.[nt 1] Chlorinated tap water decomposes rhodamine B. Rhodamine B solutions adsorb to plastics and should be kept in glass.[8] Rhodamine B is tunable around 610 nm when used as a laser dye.[9] Its luminescence quantum yield is 0.65 in basic ethanol,[10] 0.49 in ethanol,[11] 1.0,[12] and 0.68 in 94\% ethanol.[13] The fluorescence yield is temperature dependent;[14] the compound is fluxional in that its excitability is in thermal equilibrium at room temperature.[15] In California, rhodamine B is suspected to be carcinogenic and thus products containing it must contain a warning on its label.[16] Cases of economically motivated adulteration, where it has been illegally used to impart a red color to chili powder, have come to the attention of food safety regulators.[17]
