3-Chloro-6-ethyl-benzo[b]thiophene-2-carboxylic acid hydrazide 3-chloro-6-ethyl-1-benzothiophene-2-carbohydrazide 351000-82-3 CAS 351000-82-3

Description

Structurally, 3-Chloro-6-ethyl-benzo[b]thiophene-2-carboxylic acid hydrazide 3-chloro-6-ethyl-1-benzothiophene-2-carbohydrazide 351000-82-3 (C11H11ClN2OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 254.74 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

3-Chloro-6-ethyl-benzo[b]thiophene-2-carboxylic acid hydrazide 3-chloro-6-ethyl-1-benzothiophene-2-carbohydrazide 351000-82-3 (CAS 351000-82-3) is a high-purity analytical reference standard with the molecular formula C11H11ClN2OS and a molecular weight of 254.74 g/mol.

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.
