Chemical Structure
Description
cis-1-Amino-3-phosphonocyclobutanecarboxylic acid (CAS 189143-41-7) is a high-purity analytical reference standard with the molecular formula C5H10NO5P and a molecular weight of 195.11 g/mol.
cis-1-Amino-3-phosphonocyclobutanecarboxylic acid (C5H10NO5P) contains a carbohydrate-derived structure, an amide group, a phosphate ester group. It is notably hygroscopic, 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.
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), cis-1-Amino-3-phosphonocyclobutanecarboxylic acid 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.
