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 (1S,3R,4R)-3-[(TERT-BUTOXYCARBONYL)AMINO]-4-[(METHYLSULFONYL)OXY]CYCLOHEXANECARBOXYLIC ACID ETHYL ESTER.
(1S,3R,4R)-3-[(TERT-BUTOXYCARBONYL)AMINO]-4-[(METHYLSULFONYL)OXY]CYCLOHEXANECARBOXYLIC ACID ETHYL ESTER (CAS 365998-97-6), molecular formula C15H27NO7S and molecular weight 365.44 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C15H27NO7S, (1S,3R,4R)-3-[(TERT-BUTOXYCARBONYL)AMINO]-4-[(METHYLSULFONYL)OXY]CYCLOHEXANECARBOXYLIC ACID ETHYL ESTER 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 365.44 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.
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.
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.
