Chemical Structure
Description
3-Hydroxypyrrolidine-1-carboximidamide sulfate (CAS 1056471-60-3) is a high-purity analytical reference standard with the molecular formula C5H11N3OH2O4S and a molecular weight of 227.24 g/mol.
Owing to a carbohydrate-derived structure, an amide group, a sulfone group, 3-Hydroxypyrrolidine-1-carboximidamide sulfate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 227.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 3-Hydroxypyrrolidine-1-carboximidamide sulfate 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.
