Sodium 5-methoxy-2-methyl-4-(3-oxobutanamido)benzenesulfonate CAS 133167-77-8

Description

The occurrence of Sodium 5-methoxy-2-methyl-4-(3-oxobutanamido)benzenesulfonate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Sodium 5-methoxy-2-methyl-4-(3-oxobutanamido)benzenesulfonate (CAS 133167-77-8), molecular formula C12H14NO6SNa and molecular weight 323.30 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Sodium 5-methoxy-2-methyl-4-(3-oxobutanamido)benzenesulfonate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 323.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), Sodium 5-methoxy-2-methyl-4-(3-oxobutanamido)benzenesulfonate 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.
