1-Chloro-3-phenyl-2-propyne 3-Chloro-1-phenyl-1-propyne 3-Phenylpropargyl chloride 3355-31-5 CAS 3355-31-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Chloro-3-phenyl-2-propyne 3-Chloro-1-phenyl-1-propyne 3-Phenylpropargyl chloride 3355-31-5.

1-Chloro-3-phenyl-2-propyne 3-Chloro-1-phenyl-1-propyne 3-Phenylpropargyl chloride 3355-31-5 (CAS 3355-31-5) is a high-purity analytical reference standard with the molecular formula C9H13Cl and a molecular weight of 156.65 g/mol.

The molecular framework of 1-Chloro-3-phenyl-2-propyne 3-Chloro-1-phenyl-1-propyne 3-Phenylpropargyl chloride 3355-31-5 (C9H13Cl) is characterized by 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.
