Chemical Structure
Description
1-Amino-3-(thiophene-2-sulfonyl)propan-2-ol (CAS 1082500-83-1), molecular formula C7H11NO3S2 and molecular weight 221.30 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-Amino-3-(thiophene-2-sulfonyl)propan-2-ol (C7H11NO3S2) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
As a certified reference material (CRM), 1-Amino-3-(thiophene-2-sulfonyl)propan-2-ol 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.
