Acridine orange ( 3, 6-dimethylaminoacridine ) is a nucleic acid-selective metachromatic stain useful for cell cycle determination.

Acridine, C < sub > 13 </ sub > H < sub > 9 </ sub > N, is an organic compound and a nitrogen heterocycle.

Acridine is also used to describe compounds containing the C < sub > 13 </ sub > N tricycle.

Acridine is structurally related to anthracene with one of the central CH groups is replaced by nitrogen.

Acridine has a pKa of 5. 6, which is similar to that of pyridine.

Acridine is easily oxidized by peroxymonosulfuric acid to the acridine amine oxide.

Acridine is a known human carcinogen.

Acridine, a colorless solid, was first isolated from coal tar.

Acridine and related derivatives bind to DNA and RNA due to their abilities to intercalate.

Acridine was first isolated in 1871 by Carl Gräbe and Heinrich Caro.

Acridine occurs naturally in coal tar.

Acridine and its homologues are stable compounds of weakly basic character.

Acridine crystallizes in needles which melt at 110 ° C.

Acridine combines readily with alkyl iodides to form alkyl acridinium iodides, which are readily transformed by the action of alkaline potassium ferricyanide to N-alkyl acridones.

The stain may also be used in conjunction with acridine orange ( AO ) in viable cell counting.

The Hesperidina is a type of liqueur made from orange peels, invented in Argentina around 1890.

Arcturus is a type K1. 5 IIIpe orange giant star — the letters " pe " stand for " peculiar emission ," which indicates that the spectrum of light given off by the star is unusual and full of emission lines.

It is a dense, mobile, slightly transparent reddish-brown liquid, that evaporates easily at standard temperature and pressures to give an orange vapor ( its color resembles nitrogen dioxide ) that has a strongly disagreeable odor resembling that of chlorine.

The first balls made specifically for basketball were brown, and it was only in the late 1950s that Tony Hinkle, searching for a ball that would be more visible to players and spectators alike, introduced the orange ball that is now in common use.

Another festive moulded couscous dish, containing chicken, vegetables, spices, steamed in a mould and decorated with orange slices is called " Cuscuz de Galinha ".

Carotene is responsible for the orange colour of the carrot s and many other fruits and vegetables.

Carotene is an orange photosynthetic pigment important for photosynthesis.

They are responsible for the orange colour of the carrot, for which this class of chemicals is named, and for the colours of many other fruits and vegetables ( for example, sweet potatoes and orange cantaloupe melon ).

β-Carotene is the more common form and can be found in yellow, orange, and green leafy fruits and vegetables.

( Thiazole orange dye binds to nucleic acids of both DNA and RNA ).

Two distinct pigments have been identified in the secretions, one red ( hipposudoric acid ) and one orange ( norhipposudoric acid ).

Due to its citric acid content, orange juice is acidic, with a typical pH of around 3. 5 .< ref >

It is characterized by an orange sludge, which smells of hydrogen sulfide when treated with acid.

They tend to be very low in fruit juice, around 5-10 % or less and instead flavoured with cheap, low calorie synthetic flavouring ( isoamyl acetate for pear or banana, or mixed with malic acid to make an apple-like flavour, ethyl methylphenylglycidate for strawberry, octyl acetate for orange, allyl hexanoate for pineapple etc.

The succulent, tangy flesh is white, yellow or orange and sweet to subacid or acid, depending on the cultivar.

Acid – base titration is performed with a phenolphthalein indicator, when it is a strong acid – strong base titration, a bromthymol blue indicator in weak acid – weak base reactions, and a methyl orange indicator for strong acid – weak base reactions.

Like other colas, Spezi contains caffeine ; other ingredients include water, sugar, carbonic acid, orange juice and lemon juice.

Formulations with orange oil ( or other terpene solvents ), N-methylpyrrolidone, esters such as dibasic esters ( often dimethyl esters of shorter dicarboxylic acids, sometimes aminated, for example, adipic acid or glutamic acid ), aromatic hydrocarbons, dimethylformamide, and other solvents are known as well.

It later formed the Sunkist's Exchange By-Products Company, which developed markets for products such as citric acid, sodium citrate, lemon oil, pectin, orange oil and orange pulp.

Some azo compounds, e. g., methyl orange, are used as acid-base indicators due to the different colors of their acid and salt forms.

Helly is stable for only a few hours because the formaldehyde and dichromate components react, producing formic acid and chromic ions ; the orange solution becomes greenish.
