1-[(2-chloropyridin-3-yl)sulfonyl]piperidine-4-carboxylic acid CAS 929975-76-8

Description

The occurrence of 1-[(2-chloropyridin-3-yl)sulfonyl]piperidine-4-carboxylic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-[(2-chloropyridin-3-yl)sulfonyl]piperidine-4-carboxylic acid (CAS 929975-76-8), molecular formula C11H13ClN2O4S and molecular weight 304.75 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, 1-[(2-chloropyridin-3-yl)sulfonyl]piperidine-4-carboxylic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 304.75 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
