Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 141.17 g/mol gives 2-(Piperidin-4-ylidene)acetic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-(Piperidin-4-ylidene)acetic acid (CAS 4671-98-1), a certified reference material (molecular formula C7H11NO2, MW 141.17 g/mol) for analytical method development and quality control.
2-(Piperidin-4-ylidene)acetic acid (C7H11NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
