Structure of 5-Chlorobenzofuran, CAS 23145-05-3 — Structure · C8H5ClO

CAS number: 23145-05-3
Molecular formula: C₈H₅ClO
Molecular weight: 152.58 g/mol
Standard packing: 1kg / 25kg / 100kg

5-Chlorobenzofuran (CAS 23145-05-3) is a heterocyclic building block of formula C8H5ClO, 152.58 g/mol.

The ring is the scaffold rather than a substituent, so late-stage work happens on a ring carbon or on the carboxylic acid hanging off it. The ring constrains the geometry of the fragment, so the entry is bought for the shape it imposes on the rest of the molecule rather than for a single reactive site.

The formula C8H5ClO resolves to 8 carbons with one oxygen and one chlorine. At 8 carbons the entry is an oil or a low-melting solid, and it is handled at ambient temperature in most steps.

Handling and storage

Store closed, dry and dark. Ring oxidation and discolouration are the usual signs that a lot has been open too long.

Ordering
