3,4,9,10-Perylenetetracarboxylic Diimide
CAS:81-33-4
Molecular Formula:C24H10N2O4
Molecular Weight: 390.35g/mol
3,4,9,10-Perylenetetracarboxylic Diimide is pureple paste.The purity is not less than 95.0%(N). It can be used as the important intermediate for the synthesis of perylene dye and pigments. It is also used to colour metallic paint and  polyester dope.
In amoebic chemistry, an imide is a anatomic accumulation consisting of two carbonyl groups apprenticed to nitrogen. These compounds are structurally accompanying to acerbic anhydrides. The accord amid esters and amides and amid imides and anhydrides is analogous, the amine-derived groups are beneath reactive. In agreement of bartering applications, imides are best accepted as apparatus of high-strength polymers.
Being awful polar, imides display acceptable solubility in arctic media. The N-H centermost for imides acquired from ammonia is acerb and can participate in hydrogen bonding. Unlike the structurally accompanying acerbic anhydrides, they abide hydrolysis and some can even be recrystallized from baking water.

How to1 get 1,4,7-Trimethyl-1,4,7-triazacyclononane (stabilized with NaHCO3)?

CAS:96556-05-7
Molecular Formula:C9H21N3
Molecular Weight: 171.28g/mol
Description
1,4,7-Trimethyl-1,4,7-triazacyclononane is useful ligand for preparing transition metal complexes (1,2,3).
1,4,7-Triazacyclononane, known as "TACN" which is pronounced "tack-en," is a cyclic organic compound with the formula C6H12(NH)3. TACN is derived, formally speaking, from cyclononane by replacing three equidistant CH2 groups with NH groups. TACN is one of the oligomers derived from aziridine, C2H4NH. Other members of the series include piperazine, C4H8(NH)2, and the cyclic tetramer 1,4,7,10-tetraazacyclododecane.
TACN is a popular tridentate ligand. It is threefold symmetric and binds to one face of an octahedron of metalloids and transition metals. The (TACN)M unit is kinetically inert, allowing further synthetic transformations on the other coordination sites.
