(E)-2,3-Dimethylacryloyl chloride (E)-2-Methylcrotonoyl chloride 3-cis-Methyl-methacryloyl chloride 35660-94-7 Tigloyl chloride trans-2-Methyl-2-butenoyl chloride CAS 35660-94-7 chemical structure

Description

The occurrence of (E)-2,3-Dimethylacryloyl chloride (E)-2-Methylcrotonoyl chloride 3-cis-Methyl-methacryloyl chloride 35660-94-7 Tigloyl chloride trans-2-Methyl-2-butenoyl chloride is closely related to a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(E)-2,3-Dimethylacryloyl chloride (E)-2-Methylcrotonoyl chloride 3-cis-Methyl-methacryloyl chloride 35660-94-7 Tigloyl chloride trans-2-Methyl-2-butenoyl chloride (CAS 35660-94-7) is a high-purity analytical reference standard with the molecular formula C5H7ClO and a molecular weight of 118.56 g/mol.

The molecular framework of (E)-2,3-Dimethylacryloyl chloride (E)-2-Methylcrotonoyl chloride 3-cis-Methyl-methacryloyl chloride 35660-94-7 Tigloyl chloride trans-2-Methyl-2-butenoyl chloride (C5H7ClO) is characterized by a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
