Chemical Structure
Description
The occurrence of 6780-38-7 1,3-Dihydro-1,3-dioxo-2H-isoindole-2-acetyl chloride 2H-Isoindole-2-acetyl chloride, 1,3-dihydro-1,3-dioxo- 5-21-10-00440 (Beilstein Handbook Reference) BRN 0183000 EINECS 229-840-8 is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
6780-38-7 1,3-Dihydro-1,3-dioxo-2H-isoindole-2-acetyl chloride 2H-Isoindole-2-acetyl chloride, 1,3-dihydro-1,3-dioxo- 5-21-10-00440 (Beilstein Handbook Reference) BRN 0183000 EINECS 229-840-8 (CAS 6780-38-7), molecular formula C10H12ClNO3 and molecular weight 229.66 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 6780-38-7 1,3-Dihydro-1,3-dioxo-2H-isoindole-2-acetyl chloride 2H-Isoindole-2-acetyl chloride, 1,3-dihydro-1,3-dioxo- 5-21-10-00440 (Beilstein Handbook Reference) BRN 0183000 EINECS 229-840-8 (C10H12ClNO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 229.66 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 6780-38-7 1,3-Dihydro-1,3-dioxo-2H-isoindole-2-acetyl chloride 2H-Isoindole-2-acetyl chloride, 1,3-dihydro-1,3-dioxo- 5-21-10-00440 (Beilstein Handbook Reference) BRN 0183000 EINECS 229-840-8 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.
