Description

As a certified reference material (CRM), 2-(Naphthalen-2-ylsulfanyl)acetic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

2-(Naphthalen-2-ylsulfanyl)acetic acid (CAS 93-21-0), molecular formula C12H10O2S and molecular weight 218.27 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-(Naphthalen-2-ylsulfanyl)acetic acid (C12H10O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 218.27 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
