2,3-dichlorophenylpiperazine 2,3-dichlorophenylpiperazine 2,3-dichlorophenylpiperazine (2,3-dcpp or dcpp) is a chemical compound from the phenylpiperazine family. it is both a precursor in the synthesis of aripiprazole and one of its metabolites. it is unclear whether 2,3-dcpp is pharmacologically active as a serotonin receptor agonist similar to its close analogue 3-chlorophenylpiperazine (mcpp), though it has been shown to act as a partial agonist of the dopamine d2 and d3 receptors. 2,3-dichlorophenylpiperazine names preferred iupac name 1-(2,3-dichlorophenyl)piperazine identifiers cas number 41202-77-1 y 3d model (jsmol) interactive image chemspider 744460 y echa infocard 100.126.497 pubchem cid 851833 unii 891w3ev0b1 y comptox dashboard (epa) dtxsid90961499 inchi inchi=1s/c10h12cl2n2/c11-8-2-1-3-9(10(8)12)14-6-4-13-5-7-14/h1-3,13h,4-7h2 ykey: udqmxyjsnncras-uhfffaoysa-n yinchi=1s/c10h12cl2n2/c11-8-2-1-3-9(10(8)12)14-6-4-13-5-7-14/h1-3,13h,4-7h2key: udqmxyjsnncras-uhfffaoyahinchi=1/c10h12cl2n2/c11-8-2-1-3-9(10(8)12)14-6-4-13-5-7-14/h1-3,13h,4-7h2key: udqmxyjsnncras-uhfffaoyah smiles clc1c(cl)c(ccc1)n2ccncc2 properties chemical formula c10h12cl2n2 molar mass 231.12 g/mol appearance brown oil density 1.272g/cm3 °c melting point 242 to 244 °c (468 to 471 °f; 515 to 517 k) boiling point 365.1 °c (689.2 °f; 638.2 k) at 760mmhg hazards flash point 174.6 °c (346.3 °f; 447.8 k) except where otherwise noted, data are given for materials in their standard state (at 25 °c , 100 kpa). n verify (what is yn ?) infobox references legality 2,3-dcpp has been made illegal in japan and hungary after having been identified in seized designer drug samples. list of derivatives aripiprazole cariprazine bak 2-66 brilaroxazine (formally rp-5063) fauc-365 cjb-090 2xhcl ngb 2849 ngb 2904 fb: hcl: pg-01037 2xhcl: pg648 aripiptranyl (abilifarnate) pgx-2000001 u.s. patent 20,070,142,399 so-called r-22 so-called jjc 7−065 r-pg-648 positional isomer 3,4-dcpp, cas# 57260-67-0 the positional isomer 3,4-dichlorophenylpiperazine (3,4-dcpp) is also known, and acts as both a serotonin releaser via the serotonin transporter, and a β1-adrenergic receptor blocker, though with relatively low affinity at both targets. triple substituted the 3,4,5-trichlorophenylpiperazine ("3 stripes") is also a highly regarded arrangement & has been awarded the beecham patent of u.s. patent 4,139,621. such 3,4,5-trisubstituted aromatic entities is already known from clenbuterol. leading to cid:151687078 wo 1993021179 (ex 6 is a concrete example of this) i.e. 1-(4-amino-3,5-dichlorophenyl)-4-(4-phthalimido-1- butyl)piperazine.
