2090-54-2 O3842T8RNK N-Hydroxyethylpromethazine chloride Ammonium, (2-hydroxyethyl)dimethyl(1-methyl-2-phenothiazin-10-ylethyl)-, chloride (2-Hydroxyethyl)dimethyl(alpha-methyl-10H-phenothiazine-10-ethyl) chloride 10H-Phenothiazine-10-ethanaminium, N-(2-hydroxyethyl)-N,N,alpha-trimethyl-, chloride (9CI) Aprobit R EINECS 218-238-0 (2-Hydroxyethyl)dimethyl(1-methyl-2-phenothiazin-10-ylethyl)ammonium chloride Lergobit 1-(10-Phenothiazinylmethyl)ethyl-2-hydroxyethyldimethylammonium chloride UNII-O3842T8RNK (C19H25N2OSCl) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), 2090-54-2 O3842T8RNK N-Hydroxyethylpromethazine chloride Ammonium, (2-hydroxyethyl)dimethyl(1-methyl-2-phenothiazin-10-ylethyl)-, chloride (2-Hydroxyethyl)dimethyl(alpha-methyl-10H-phenothiazine-10-ethyl) chloride 10H-Phenothiazine-10-ethanaminium, N-(2-hydroxyethyl)-N,N,alpha-trimethyl-, chloride (9CI) Aprobit R EINECS 218-238-0 (2-Hydroxyethyl)dimethyl(1-methyl-2-phenothiazin-10-ylethyl)ammonium chloride Lergobit 1-(10-Phenothiazinylmethyl)ethyl-2-hydroxyethyldimethylammonium chloride UNII-O3842T8RNK meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
