1-Chloro-2-methyl-3-pentyn-2-ol CAS 115823-68-2

Description

The occurrence of 1-Chloro-2-methyl-3-pentyn-2-ol 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.

1-Chloro-2-methyl-3-pentyn-2-ol (CAS 115823-68-2) is a high-purity analytical reference standard with the molecular formula C6H9ClO and a molecular weight of 132.59 g/mol.

Structurally, 1-Chloro-2-methyl-3-pentyn-2-ol (C6H9ClO) contains a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 132.59 g/mol, it falls into the low-molecular-weight range. 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.

As a certified reference material (CRM), 1-Chloro-2-methyl-3-pentyn-2-ol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
