Chemical Structure
Description
As a certified reference material (CRM), sec-butyl 4-methylbenzenesulfonate 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.
sec-butyl 4-methylbenzenesulfonate (CAS 715-11-7), molecular formula C11H16O3S and molecular weight 228.31 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, sec-butyl 4-methylbenzenesulfonate (C11H16O3S) 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 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 228.31 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
