2-[n-(butan-2-yl)2-chloropyridine-3-sulfonamido]acetic acid CAS 1179972-08-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-[n-(butan-2-yl)2-chloropyridine-3-sulfonamido]acetic acid.

2-[n-(butan-2-yl)2-chloropyridine-3-sulfonamido]acetic acid (CAS 1179972-08-7), molecular formula C11H15ClN2O4S and molecular weight 306.77 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, chlorine substitution, 2-[n-(butan-2-yl)2-chloropyridine-3-sulfonamido]acetic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 306.77 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).

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.

As a certified reference material (CRM), 2-[n-(butan-2-yl)2-chloropyridine-3-sulfonamido]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.
