Is 4-iodobutyrophenone a synonym for 5-Iodo-1-phenylpentan-1-one?

No. 4-Iodobutyrophenone has the structure Ph–CO–(CH2)3–I, whereas 5-Iodo-1-phenylpentan-1-one has Ph–CO–(CH2)4–I. They differ by one methylene group and are not synonyms. For CAS 66860-64-8, confirm the five-carbon ketone chain, the formula C11H13IO and an agreed chromatographic or spectral identity method.

Which quality points should be set for 5-Iodo-1-phenylpentan-1-one?

Specify chromatographic assay, identity, physical form or melting range, water, residual solvents and limits for relevant starting-material, deiodinated or elimination impurities. Appearance, sample method, package compatibility and light or temperature protection should follow stability data for the offered grade rather than being assumed from the CAS number.

5-Iodo-1-phenylpentan-1-one CAS 66860-64-8

5-Iodo-1-phenylpentan-1-one, also called 5-iodovalerophenone or 1-phenyl-5-iodopentan-1-one, CAS 66860-64-8, is an iodo-functionalized aromatic ketone (C₁₁H₁₃IO, MW 288.13 g/mol). It is supplied as a research and synthesis intermediate with lot-specific identity, assay, impurity and physical-form data. Alkyl iodides are condition-sensitive, so confirm light exposure, storage, analytical timing and route-critical impurities before use.

Identity and physicochemical profile

Item	Technical guidance
Product identity	5-Iodo-1-phenylpentan-1-one; 5-iodovalerophenone
CAS number	66860-64-8
Formula / molecular weight	C₁₁H₁₃IO / 288.13 g/mol
Functional character	A terminal primary iodide and an aryl ketone separated by a four-carbon chain
Key purchase controls	Identity, chromatographic assay, positional isomers, residual starting materials, dehalogenation products, water and color

Applications and grade selection

5-Iodo-1-phenylpentan-1-one may be evaluated in controlled substitution, cyclization and functional-group-conversion routes used to prepare more complex research intermediates. The actual reaction value depends on the buyer’s nucleophile, solvent, temperature and impurity tolerance, so application performance should be confirmed at small scale.

Agree the identity technique, assay method and limits for unreacted precursors, positional isomers and degradation products.
Check color and chromatographic profile promptly after receipt and record storage and sampling conditions.
Run a representative reaction before authorizing project-volume supply.

Storage and handling

Keep the container tightly closed and protected from light, heat and incompatible reagents under the conditions stated in the current documentation. Minimize repeated opening and follow the supplier’s instructions for atmosphere, temperature and retest period.

Safety, documentation and procurement

Handle as a reactive organoiodine synthesis intermediate using suitable gloves, eye protection and ventilation according to the current SDS. An inquiry should define specification, intended reaction, sample or project quantity, packaging, destination and documentation.
