The substance, IUPAC name (29H,31H-phthalocyaninato(2−)-N29,N30,N31,N32)copper(II), is known by many names [2] such as monastral blue, phthalo blue, helio blue, [3] thalo blue, Winsor blue, [4] phthalocyanine blue, C.I. Pigment Blue 15:2, [5] [6] copper phthalocyanine blue, [7] copper tetrabenzoporphyrazine, [8] Cu-phthaloblue, [9] P.B.15.2, [10] [11] [12] C.I. 74160, [13] [14] [15] and ...
Phthalocyanine green is derived from phthalocyanine blue by chlorination in the presence of aluminium trichloride. The stoichiometry for the complete chlorination is shown: [1] Cu(C 32 H 16 N 8) + 16 Cl 2 → Cu(C 32 N 8 Cl 16) + 16 HCl. In practice, this pigment is a mixture of isomers and degrees of chlorination.
Phthalocyanine (H 2 Pc) is a large, aromatic, macrocyclic, organic compound with the formula (C 8 H 4 N 2) 4 H 2 and is of theoretical or specialized interest in chemical dyes and photoelectricity. It is composed of four isoindole units [ a ] linked by a ring of nitrogen atoms.
Copper phthalocyanine; Aluminosilicate pigments. Ultramarine (PB29): a synthetic or naturally occurring sulfur containing silicate mineral - Na 8–10 Al 6 Si 6 O 24 S 2–4 (generalized formula) Persian blue: made by grinding up the mineral Lapis lazuli.
Micromass cultures of C3H-10T1/2 cells at varied oxygen tensions stained with Alcian blue. Alcian blue (/ ˈ æ l ʃ ə n /) is any member of a family of polyvalent basic dyes, of which the Alcian blue 8G (also called Ingrain blue 1, and C.I. 74240, formerly called Alcian blue 8GX from the name of a batch of an ICI product) has been historically the most common and the most reliable member.

Laundry detergent fluorescing under ultraviolet light. Optical brighteners, optical brightening agents (OBAs), fluorescent brightening agents (FBAs), or fluorescent whitening agents (FWAs), are chemical compounds that absorb light in the ultraviolet and violet region (usually 340-370 nm) of the electromagnetic spectrum, and re-emit light in the blue region (typically 420-470 nm) through the ...
It is a synthetic green pigment from the group of phthalocyanines, a complex of copper(II) with chlorinated phthalocyanine. It is a soft green powder, which is insoluble in water. [ 2 ] It is a bright, high intensity colour used in oil and acrylic based artist's paints , and in other applications.
Micrograph of the pons using a hematoxylin & eosin-luxol fast blue stain. Coronal section of a mouse brain stained with Hematoxylin & LFB. Luxol fast blue stain, abbreviated LFB stain or simply LFB, is a commonly used stain to observe myelin under light microscopy, first developed by Heinrich Klüver and Elizabeth Barrera in 1953. [1]
