2-{[(2Z)-2-amino-2-{[(pyridin-4-yl)formamido]imino}ethyl]sulfanyl}pyridin-1-ium-1-olate CAS 338418-79-4 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 2-{[(2Z)-2-amino-2-{[(pyridin-4-yl)formamido]imino}ethyl]sulfanyl}pyridin-1-ium-1-olate.

2-{[(2Z)-2-amino-2-{[(pyridin-4-yl)formamido]imino}ethyl]sulfanyl}pyridin-1-ium-1-olate (CAS 338418-79-4) is a high-purity analytical reference standard with the molecular formula C13H13N5O2S and a molecular weight of 303.34 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 2-{[(2Z)-2-amino-2-{[(pyridin-4-yl)formamido]imino}ethyl]sulfanyl}pyridin-1-ium-1-olate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 303.34 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), 2-{[(2Z)-2-amino-2-{[(pyridin-4-yl)formamido]imino}ethyl]sulfanyl}pyridin-1-ium-1-olate 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.
