Based on its molecular formula C13H21NO, 84-83-3 Acetaldehyde, (1,3-dihydro-1,3,3-trimethyl-2H-indol-2-ylidene)- 1,3-Dihydro-1,3,3-trimethyl-2H-indol-2-ylidene acetaldehyde delta2,alpha-Indolineacetaldehyde, 1,3,3-trimethyl- (8CI) delta(sup 2,alpha)-Indolineacetaldehyde, 1,3,3-trimethyl- (7CI,8CI) Acetaldehyde, 2-(1,3-dihydro-1,3,3-trimethyl-2H-indol-2-ylidene)- (1,3-Dihydro-1,3,3-trimethyl-2H-indol-2-ylidene)acetaldehyde EINECS 201-565-8 Fischer's aldehyde Fisher's aldehyde 2-(Formylmethylene)-1,3,3-trimethylindoline NSC 68048 delta(sup 2,alpha)-Indolinacetaldehyde, 1,3,3-trimethyl- (6CI) Tribasenaldehyde 1,3,3-Trimethyl-2-(formylmethylene)indoline 1,3,3-Trimethyl-delta2,alpha-indolineacetaldehyde (1,3,3-Trimethylindolin-2-ylidene)acetaldehyde contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 207.31 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), 84-83-3 Acetaldehyde, (1,3-dihydro-1,3,3-trimethyl-2H-indol-2-ylidene)- 1,3-Dihydro-1,3,3-trimethyl-2H-indol-2-ylidene acetaldehyde delta2,alpha-Indolineacetaldehyde, 1,3,3-trimethyl- (8CI) delta(sup 2,alpha)-Indolineacetaldehyde, 1,3,3-trimethyl- (7CI,8CI) Acetaldehyde, 2-(1,3-dihydro-1,3,3-trimethyl-2H-indol-2-ylidene)- (1,3-Dihydro-1,3,3-trimethyl-2H-indol-2-ylidene)acetaldehyde EINECS 201-565-8 Fischer's aldehyde Fisher's aldehyde 2-(Formylmethylene)-1,3,3-trimethylindoline NSC 68048 delta(sup 2,alpha)-Indolinacetaldehyde, 1,3,3-trimethyl- (6CI) Tribasenaldehyde 1,3,3-Trimethyl-2-(formylmethylene)indoline 1,3,3-Trimethyl-delta2,alpha-indolineacetaldehyde (1,3,3-Trimethylindolin-2-ylidene)acetaldehyde meets the metrological traceability requirements of ISO/IEC 17025 laboratories.
