It started in a small neighborhood store downtown Athens in 1950 [ 2 ] and today has a network of over 90 stores, [ 2 ] in Greece and Cyprus, both corporate and franchise, as well as two online stores, kotsovolos.gr and kotsovolos.cy.
Cyanines, also referred to as tetramethylindo (di)-carbocyanines[ 1] are a synthetic dye family belonging to the polymethine group. Although the name derives etymologically from terms for shades of blue, the cyanine family covers the electromagnetic spectrum from near IR to UV . Chemically, cyanines are a conjugated system between two nitrogen ...
Nicotinonitrile or 3-cyanopyridine is an organic compound with the formula NCC 5 H 4 N. The molecule consists of a pyridine ring with a nitrile group attached to the 3-position. A colorless solid, it is produced by ammoxidation of 3-methylpyridine: [2] H 3 CC 5 H 4 N + NH 3 + 1.5 O 2 → NCC 5 H 4 N + 3 H 2 O. Nicotinonitrile is a precursor to ...

Tricyclohexylphosphine is the tertiary phosphine with the formula P ( C 6 H 11) 3. Commonly used as a ligand in organometallic chemistry, it is often abbreviated to PCy 3, where Cy stands for cyclohexyl. It is characterized by both high basicity (p Ka = 9.7) [ 1] and a large ligand cone angle (170°). [ 2][ 3] Important complexes containing P ...
5-HIAA is the major urinary metabolite of serotonin, a ubiquitous bioactive amine. Serotonin, and consequently 5-HIAA, are produced in excess by most carcinoid tumors, especially those producing the carcinoid syndrome of flushing, hepatomegaly (enlarged liver ), diarrhea, bronchospasm, and heart disease. Quantitation of urinary 5-HIAA is the ...
is the least stable, while 7. H. is the most. Hydrogen is the only element whose isotopes have different names that remain in common use today: the 2. H. (or hydrogen-2) isotope is deuterium [ 6] and the 3. H. (or hydrogen-3) isotope is tritium. [ 7] The symbols D and T are sometimes used for deuterium and tritium.
N-(4-Amino-3-pyridinyl)acetamide or 3-N-acetylamifampridine, the metabolite Amifampridine is quickly and almost completely (93–100%) absorbed from the gut. In a study with 91 healthy subjects, maximum amifampridine concentrations in blood plasma were reached after 0.6 (±0.25) hours when taken without food, or after 1.3 (±0.9) hours after a ...
