4-Allyl-5-(5-methyl-4-phenylthiophen-3-yl)-4H-1,2,4-triazole-3-thiol CAS 862649-72-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Allyl-5-(5-methyl-4-phenylthiophen-3-yl)-4H-1,2,4-triazole-3-thiol.

4-Allyl-5-(5-methyl-4-phenylthiophen-3-yl)-4H-1,2,4-triazole-3-thiol (CAS 862649-72-7), molecular formula C16H15N3S2 and molecular weight 313.44 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4-Allyl-5-(5-methyl-4-phenylthiophen-3-yl)-4H-1,2,4-triazole-3-thiol (C16H15N3S2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 313.44 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.
