4-(2-thiazol-5-ylethynyl)-1,2-benzoxazol-3-amine CAS 2526799-34-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(2-thiazol-5-ylethynyl)-1,2-benzoxazol-3-amine.

4-(2-thiazol-5-ylethynyl)-1,2-benzoxazol-3-amine (CAS 2526799-34-6), molecular formula C12H7N3OS and molecular weight 241.27 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4-(2-thiazol-5-ylethynyl)-1,2-benzoxazol-3-amine (C12H7N3OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. 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 241.27 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
