Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including OEU4AZC07S 3570-55-6 Bis(2-mercaptoethyl) sulfide Ethanethiol, 2,2'-thiobis- Ethanethiol, 2,2'-thiodi- (8CI) 2,2'-Thiodiethanethiol AI3-62012 Bis(mercaptoethyl) sulfide 2,2'-Dimercaptodiethyl sulfide EINECS 222-671-0 2-Mercaptoethyl sulfide 1-Mercapto-2-(mercaptoethylthio)ethane NSC 4766 TDT 3-Thia-1,5-pentanedithiol UNII-OEU4AZC07S.

OEU4AZC07S 3570-55-6 Bis(2-mercaptoethyl) sulfide Ethanethiol, 2,2'-thiobis- Ethanethiol, 2,2'-thiodi- (8CI) 2,2'-Thiodiethanethiol AI3-62012 Bis(mercaptoethyl) sulfide 2,2'-Dimercaptodiethyl sulfide EINECS 222-671-0 2-Mercaptoethyl sulfide 1-Mercapto-2-(mercaptoethylthio)ethane NSC 4766 TDT 3-Thia-1,5-pentanedithiol UNII-OEU4AZC07S (CAS 3570-55-6) is a high-purity analytical reference standard with the molecular formula C4H10S3 and a molecular weight of 154.32 g/mol.

Owing to sulfur-containing functionality, OEU4AZC07S 3570-55-6 Bis(2-mercaptoethyl) sulfide Ethanethiol, 2,2'-thiobis- Ethanethiol, 2,2'-thiodi- (8CI) 2,2'-Thiodiethanethiol AI3-62012 Bis(mercaptoethyl) sulfide 2,2'-Dimercaptodiethyl sulfide EINECS 222-671-0 2-Mercaptoethyl sulfide 1-Mercapto-2-(mercaptoethylthio)ethane NSC 4766 TDT 3-Thia-1,5-pentanedithiol UNII-OEU4AZC07S is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 154.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
