Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (R)-3-Formyl-2,2,5,5-tetramethylthiazolidine-4-carboxylic acid.
CATO supplies (R)-3-Formyl-2,2,5,5-tetramethylthiazolidine-4-carboxylic acid (CAS 40626-24-2), a certified reference material (molecular formula C9H15NO3S, MW 217.29 g/mol) for analytical method development and quality control.
Based on its molecular formula C9H15NO3S, (R)-3-Formyl-2,2,5,5-tetramethylthiazolidine-4-carboxylic acid contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 217.29 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
