Structure of 4,5,6,7-Tetrahydrobenzo[b]thiophene-2-carboxylic acid, CAS 40133-07-1 — Structure · C9H10O2S

CAS number: 40133-07-1
Molecular formula: C₉H₁₀O₂S
Molecular weight: 182.24 g/mol
Standard packing: 1kg / 25kg / 100kg

4,5,6,7-Tetrahydrobenzo[b]thiophene-2-carboxylic acid is catalogued as an acid: CAS 40133-07-1, formula C9H10O2S, molecular weight 182.24.

The carboxylic acid is activated in situ for amidation or esterification, or used directly for salt formation; the free acid is also the form that stores best. 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 C9H10O2S resolves to 9 carbons with 2 oxygens and one sulfur. A 9-carbon chain sits between volatility and lipophilicity, which is the range most often used when a fragment has to stay in the organic phase without being waxy.

Handling and storage

Acids are stored away from amines and bases, and the container is kept closed because the material is hygroscopic.

Ordering

Shipped in 1kg / 25kg / 100kg units with a batch certificate of analysis and a GHS safety data sheet; a smaller sample can be quoted separately. Nothing on this page should be read as a guaranteed minimum. The number that applies is the one on the certificate for the lot you receive.
