Proflavin hemisulfate hydrate CAS 1811-28-5

Description

Compared with other compounds in its class, the molecular weight of 339.45 g/mol gives Proflavin hemisulfate hydrate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Proflavin hemisulfate hydrate (CAS 1811-28-5), molecular formula C13H25N3H2O4SH2O and molecular weight 339.45 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, Proflavin hemisulfate hydrate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 339.45 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), Proflavin hemisulfate hydrate 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.
