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-Chlorobenzamido)-4,5,6,7-tetrahydrobenzo[d]thiazole-4-carboxylic acid.
2-(4-Chlorobenzamido)-4,5,6,7-tetrahydrobenzo[d]thiazole-4-carboxylic acid (CAS 1019108-36-1) is a high-purity analytical reference standard with the molecular formula C15H13ClN2O3S and a molecular weight of 336.79 g/mol.
Structurally, 2-(4-Chlorobenzamido)-4,5,6,7-tetrahydrobenzo[d]thiazole-4-carboxylic acid (C15H13ClN2O3S) 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 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 336.79 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
