2-[2-(2-Chloro-2-oxoethoxy)ethoxy]acetyl chloride

2-[2-(2-Chloro-2-oxoethoxy)ethoxy]acetyl chloride is the PubChem IUPAC name linked to CAS 31255-09-1. PubChem assigns CID 11106745, molecular formula C6H8Cl2O4, SMILES C(COCC(=O)Cl)OCC(=O)Cl, and InChIKey XIZKIJKZPGHKKR-UHFFFAOYSA-N. Those identifiers establish the corrected preferred wording for the structure formerly labeled “3,6-dioxa-1,8-octanoyl dichloride.”

The graph is an open chain containing six carbons, four oxygens, and two chlorines. At each end, an acetyl chloride unit contributes a carbonyl oxygen and a chlorine bonded through the acyl carbon. Two additional oxygens occur as ether links within the intervening carbon chain. The SMILES encodes every atom as one connected molecule, without a detached chloride or other counterion. It also contains no ring closure and no stereochemical marker. Formula C6H8Cl2O4 agrees with the two carbonyl groups, two ether oxygens, and paired terminal chlorines. The bracketed IUPAC wording traces one end through successive oxoethoxy and ethoxy segments to the other acetyl chloride, making the bonding sequence explicit rather than relying on the compressed former label.

An inquiry to Rlavie should include CAS 31255-09-1, CID 11106745, the requested quantity, and request-specific information relevant to the identity check. Supply a MOL or SDF structure file when the chain is communicated graphically, and verify that it matches C(COCC(=O)Cl)OCC(=O)Cl. The InChIKey XIZKIJKZPGHKKR-UHFFFAOYSA-N provides a compact comparison point for linking the message to this exact two-ended structure file record.
