4-(Bromomethyl)-2,2-dimethyl-1,3-dioxolane

CAS 36236-76-7 corresponds to 4-(Bromomethyl)-2,2-dimethyl-1,3-dioxolane, molecular formula C6H11BrO2. PubChem identifies the compound as CID 169759 and supplies SMILES CC1(OCC(O1)CBr)C. Its InChIKey is ZOPZKFNSQYCIPP-UHFFFAOYSA-N. The official title and computed IUPAC name both adopt the ring spelling “dioxolane,” while the older “dioxalane” label appears only as a deposited synonym for this same structure.

The 1,3-dioxolane unit is a five-membered ring containing two oxygen atoms separated by carbon 2. That carbon carries two methyl groups, and carbon 4 bears a bromomethyl substituent. These features account for six carbons, eleven hydrogens, one bromine, and two oxygens in C6H11BrO2. The PubChem graph contains one connected component and no counterion. It does not encode an absolute configuration at the substituted ring carbon, so the standardized name deliberately omits any R or S prefix. Correcting the vowel in the ring name changes the label, not the verified molecular graph.

An exact inquiry should reference CAS 36236-76-7 and the standardized 1,3-dioxolane name. State the amount of interest, provide a contact address, and describe any identity records that should be reviewed with the response. A requester working from structural data can cross-check PubChem CID 169759 or InChIKey ZOPZKFNSQYCIPP-UHFFFAOYSA-N. Rlavie can rely on those identifiers to distinguish this entry from chloromethyl analogues, differently substituted dioxolanes, or a stereospecific record. Retaining both methyl locants and the bromomethyl position is essential because the formula alone does not communicate ring substitution.
