phenylthioacetic acid CAS 103-04-8 chemical structure

Description

CATO supplies phenylthioacetic acid (CAS 103-04-8), a certified reference material (molecular formula C8H14O2S, MW 174.26 g/mol) for analytical method development and quality control.

Structurally, phenylthioacetic acid (C8H14O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 174.26 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.
