2-((4,5-Bis(4-chlorophenyl)-4h-1,2,4-triazol-3-yl)thio)acetic acid CAS 305337-58-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-((4,5-Bis(4-chlorophenyl)-4h-1,2,4-triazol-3-yl)thio)acetic acid.

2-((4,5-Bis(4-chlorophenyl)-4h-1,2,4-triazol-3-yl)thio)acetic acid (CAS 305337-58-0) is a high-purity analytical reference standard with the molecular formula C16H11Cl2N3O2S and a molecular weight of 380.25 g/mol.

Structurally, 2-((4,5-Bis(4-chlorophenyl)-4h-1,2,4-triazol-3-yl)thio)acetic acid (C16H11Cl2N3O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 380.25 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
