Chemical Structure
Description
The occurrence of 4-(Isopropylthio)butanoic acid is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-(Isopropylthio)butanoic acid (CAS 79313-54-5), molecular formula C7H14O2S and molecular weight 162.25 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-(Isopropylthio)butanoic acid (C7H14O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 162.25 g/mol, it falls into the medium-molecular-weight range.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
