Barium sulfate (or sulphate) is the inorganic compound with the chemical formula BaSO4. It is a white crystalline solid that is odorless and insoluble in water. It occurs as the mineral barite, which is the main commercial source of barium and materials prepared from it.
CALCIUM CHROMATE (13765-19-0, 12205-18-4, 53568-70-0)
calcium chromate(VI), dihydrate · calcium chromate(VI)
Calcium chromate (CaCrO4) is a bright yellow solid. It normally occurs as the dihydrate, although the very rarely natural (mineral) form, known as hashemite, is anhydrous.
TITANIUM DIOXIDE (1317-80-2, 1317-70-0, 13463-67-7, 98084-96-9)
Titania · rutile · anatase
Titanium dioxide, also known as titanium(IV) oxide or titania, is the naturally occurring oxide of titanium, chemical formula TiO 2. When used as a pigment, it is called titanium white, Pigment White 6 (PW6), or CI 77891. Generally it is sourced from ilmenite, rutile and anatase.
lead tetroxide (1314-41-6)
azarcon · red lead oxide · lead tetraoxide
Chromium(III) oxide (1308-38-9, 196696-68-1)
chromic oxide · chromium sesquioxide · dichromium trioxide
Chromium(III) oxide is the inorganic compound of the formula Cr 2O 3. It is one of the principal oxides of chromium and is used as a pigment. In nature, it occurs as the rare mineral eskolaite.
Diarylanilide Yellow (6358-85-6)
benzidine yellow · pigment yellow 12 · C.I. pigment yellow 12
FERROUS OXIDE (17125-56-3, 1345-25-1)
Iron(II) oxide or ferrous oxide is the inorganic compound with the formula FeO. Its mineral form is known as wüstite. One of several iron oxides, it is a black-colored powder that is sometimes confused with rust, the latter of which consists of hydrated iron(III) oxide (ferric oxide).
INDIGO (68651-46-7, 482-89-3)
Indigo Blue · Indigo Carmine · indigotin
Indigo is a deep and rich color close to the color wheel blue (a primary color in the RGB color space), as well as to some variants of ultramarine. It is traditionally regarded as a color in the visible spectrum, as well as one of the seven colors of the rainbow: the color between blue and violet; however, sources differ as to its actual position in the electromagnetic spectrum. The color indigo is named after the indigo dye derived from the plant Indigofera tinctoria and related species.
bilirubin (93891-87-3, 18422-02-1, 635-65-4)
Hematoidin · Calcium Bilirubinate · delta Bilirubin
Bilirubin (formerly referred to as haematoidin and discovered by Rudolf Virchow in 1847) is a yellow compound that occurs in the normal catabolic pathway that breaks down heme in vertebrates. This catabolism is a necessary process in the body's clearance of waste products that arise from the destruction of aged red blood cells. First the hemoglobin gets stripped of the heme molecule which thereafter passes through various processes of porphyrin catabolism, depending on the part of the body in which the breakdown occurs.
Manganese dioxide (1313-13-9)
pyrolusite · vernadite
Manganese(IV) oxide is the inorganic compound with the formula MnO 2. This blackish or brown solid occurs naturally as the mineral pyrolusite, which is the main ore of manganese and a component of manganese nodules. The principal use for MnO 2 is for dry-cell batteries, such as the alkaline battery and the zinc-carbon battery.
Zinc Phosphate (13847-22-8, 7779-90-0)
Zinc phosphate (Zn3(PO4)2) is an inorganic chemical compound used as a corrosion resistant coating on metal surfaces either as part of an electroplating process or applied as a primer pigment (see also red lead). It has largely displaced toxic materials based on lead or chromium, and by 2006 it had become the most commonly used corrosion inhibitor. Zinc phosphate coats better on a crystalline structure than bare metal, so a seeding agent is often used as a pre-treatment.
Alizarin (72-48-0, 1322-60-7)
alizarine · alizarin red · 1,2-dihydroxyanthraquinone
Alizarin or 1,2-dihydroxyanthraquinone (also known as Mordant Red 11 and Turkey Red) is an organic compound with formula C 14H 8O 4 that has been used throughout history as a prominent red dye, principally for dyeing textile fabrics. Historically it was derived from the roots of plants of the madder genus. In 1869, it became the first natural pigment to be synthesised synthetically.
Pigment Blue 16 · dehydrophthalocyanine · dinuclear phthalocyanine H2Pc-H2Pc
Phthalocyanine is an organic compound with the formula (C8H4N2)4H2. It is classified as an aromatic macrocyclic compound. The organic compound is only of theoretical or specialized interest, but its metal complexes are valuable as dyes, pigments, and catalysts.
Naphthol AS (92-77-3)
3-hydroxy-2-naphthanilide · naphthol AS, 14C-labeled cpd · naphthol AS, monosodium salt
Pyocyanin (PCN−) is one of the many toxins produced and secreted by the Gram negative bacterium Pseudomonas aeruginosa. Pyocyanin is a blue, secondary metabolite with the ability to oxidise and reduce other molecules and therefore can kill microbes competing against P. aeruginosa as well as mammalian cells of the lungs which P.
C.I. Pigment Red 170 (2786-76-7)
Naphthol Red (Pigment red 170 or PR170) is an organic pigment extensively used in automotive coatings and painting. It is produced synthetically by converting p-aminobenzamide into the corresponding diazonium compound followed by diazotation with 3-hydroxy-2-naphththoic acid (2-ethoxy)anilide ("Naphtol AS-PH" dye precursor). In the solid state the hydrazo tautomer forms and several crystal structures exist.
